Opinion
Mаrch 28,1971, was a clear day. A 177 Cessna Cardinal took off from Warner Springs Airport. Shortly after takeoff the aircraft crashed and burned. Helen M. McGee was burned. Her bums were so severe both legs had to be amputated. McGee sued the manufacturer of the airplane, defendant Cessna Aircraft Company (Cessna). A jury trial resulted in judgment for Cessna. We reversed, holding McGee should have been allowed to present her cause on a theory of strict liability based on Cessna’s failure to design a sufficiently crashworthy aircraft. 1
McGee presented her case to a second jury. The jury returnеd judgment for Cessna. McGee complains this judgment is the result of the trial court’s failure to properly limit the evidence and correctly instruct the jury. Five questions are presented in her appeal.
Facts
Although we reviewed the facts in
McGee
v.
Cessna Aircraft Co., supra,
On the day of the accident, Hedger was to observe McGee and a friend and help them with cross-country flying and navigation skills in preparation for a contest. McGee was to fly from Warner Hot Springs to Bakersfield and her friend from Bakersfield to the Nut Tree. The crash occurred approximately a *183 mile from the airport about three minutes after they took off from Warner Hot Springs.
The aircraft took off going east into a wind estimated at around 10 to 15 nautical miles per hour. Only a few moments after takeoff the aircraft turned and crashed into a small hill. The crash site was approximately 135 to 180 feet above the level of the airport. The shortest distance between Warner Hot Springs and Bakersfield would have been to execute a left hand turn from the runway. However, had McGee turned to the right she would have been flying over lower terrain.
When the aircraft сrashed, McGee and Hedger were rendered unconscious. The two passengers in the rear seats were thrown forward but not critically injured. All four occupants were wearing seat belts but the aircraft was not equipped with shoulder harnesses. The two passengers in the rear were able to get out of the airplane through the right door. A fire began almost immediately. The passengers tried to get McGee out but they were not strong enough. They dragged Hedger from the aircraft and returned for McGee. McGee’s legs were on fire.
Other than some superficial facial injuries, McGee’s injuries consisted of third and fourth degree bums. 3 Muscle and bone tissue in both legs were burned; burns on her left leg were concentrated in the calf and the foot extending upwards to the groin area, bums in the right leg were primarily below the knee but extended into the buttock. Both legs were amputated. The amputations, revisions of the stumps, and skin grafting required six separate surgeries, consisting of over 16 hours of surgical procedures.
After 17 months, McGee attempted to return to work. Eventually, due to the pain and the effects of her medication, she had to quit and she has been unemployed since.
Experts on both sides testified as to general principles of flight, aerodynamics, flight regulations, standard flying procedures particularly those relating to Warner Hot Springs Airport, and the history, design, development and specifications of the 177 Cardinal Cessna relating both to the aircraft’s flying capabilities and its crashworthiness. Rather than review this extensive and complicated evidence, we will discuss only that testimony relevant to the issues raised in this appeal.
*184 Discussion
Both parties agree McGee’s severe and permanent injuries were caused by the post-crash fire. McGee maintains the fire was cаused by Cessna’s failure to design a sufficiently crashworthy aircraft. She asks “Why, in a clearly survivable crash, the aircraft did not protect [her] from enhanced injuries sustained by collision with the interior of the aircraft and exposure to the fire?” Cessna rebuts claiming the fire was a natural result of a violent crash and the Cessna 177 Cardinal was sufficiently crashworthy.
McGee asserts this court has the power to determine the extent to which the issues in a complex case may be limited on retrial.
(Hasson
v.
Ford Motor Co.
(1977)
Cessna argues even if plaintiff’s case were restricted to crashworthiness, Cessna should be permitted to attempt to show the crash itself was of such severity it was the sole proximate cause of the injuries and supersedes any defective design. In
Self v. General Motors Corp.
(1974)
In
Trust Corp. of Mont.
v.
Piper Aircraft Corp.
(D.Mont. 1981)
Even though some of McGee’s conduct would be relevant on a strict liability for enhanced injuries cause of action in order to determine such things as speed, angle, and direction of impact, under California law Evidence Code section 352, evidence which is more prejudicial than probative must be excluded. In this trial much evidence was admitted relevant to Cessna’s negligence and strict liability for airworthiness design but irrelevant to whether the aircraft was crashworthy. On negligence theory as to the cause of the crash this evidence would be more probative than prejudicial, but on strict liability for crashworthiness much of this evidence is clearly prejudicial and should be excluded. For example, evidence showed McGee and her flight instructor, Hedger, were romantically involved. Hedger convinced McGee to tell the FAA she had more flying experience than she did. McGee inflated her flying hours in a report to the FAA in order to insure Hedger’s insurance policy would cover the accident. Both Hedger and McGee denied they were controlling the aircraft when it crashed. On a strict liability for crashworthiness theory this extremely prejudicial evidence would not be probative for any cause of the fire relating to the speed, angle, direction, weight, etc., of the impact.

Daly
v.
General Motors Corp., supra,

McGee asserts the trial court’s failure to instruct the jury to shift the burden of proving proximate cause to Cessna if Cessna violated federal air regulations constitutes reversible error. The jury instructions included Federal Aviation Regulation 23.1191 4 concerning specifications for aircraft firewalls *186 and Federal Aviation Regulation (F.A.R.) 23.561 5 providing for protection оf the occupants in emergency landing conditions.
McGee proffered an instruction which would shift the burden of proof on the issue of causation based on these regulations. 6 McGee argues the trial court should not have refused this instruction under Evidence Code section 669, subdivision (a). Evidence Code section 669, subdivision (a) provides:
“(a) The failure of a person to exercise due care is presumed if:
“(1) He violated a statute, ordinance, or regulation of a public entity;
“(2) The violation proximately caused death or injury to person or property;
“(3) The death or injury resulted from an occurrence of the nature which the statutе, ordinance, or regulation was designed to prevent; and
“(4) The person suffering the death or the injury to his person or property was one of the class of persons for whose protection the statute, ordinance or regulation was adopted.” McGee cites these regulations to prove both negligence per se and as proof the aircraft was defectively designed because violation of the F.A.R. is proof of a design defect. Under both a theory of negligence per se and strict liability for design defect, the burden of proof is on Cessna to provе the defect was not a proximate cause of the injury.
Cessna’s witness, Alvarez, testified the aluminum firewall fittings on the Cessna Cardinal could not resist flame penetration for 15 minutes as required by the F.A.R. In fact, the fittings could only resist flame penetration for 10 to 40 seconds. There is no question but that McGee was one of the persons belonging to the class of persons protected by the statute and that the fire caused an injury the nature of which the statute was designed to prevent. A Federal Aviation Safety Regulation is entitled to as much weight as a statute, ordinance
*187
or regulation of a public еntity under Evidence Code section 669, subdivision (a).
(Lightenburger
v.
United States
(C.D.Cal. 1969)
Similarly, McGee uses the violation of the F.A.R. to show a design defect. An inference of defective design based on the F.A.R. is nеcessary because the fire destroyed the accumulator tank and much of the evidence, and because the experts disagree as to whether the fire entered the cockpit through the firewall via the fittings or through the doors which were blown off or open during the accident.
The Law Revision Commission comment to California Evidence Code section 500 states: “In determining whether the normal allocation of the burden of proof should be altered, the courts consider a number of factors: the knowledge of the parties concerning the particular fact, the availability of the evidence to the parties, the most desirable result in terms of public policy in the absence of proof of the particular fact, and the probability of the existence or nonexistence of the fact. ” This court has held “one of the principal purposes behind the strict product liability doctrine is to relieve an injured plaintiff of many of the onerous evidentiary burdens inherent in a negligence cause of action.”
(McGee
v.
Cessna Aircraft Co., supra,
This result is consistent with the recent case
Campbell
v.
General Motors Corp.
(1982)
Even though the issues in
Campbell
arose after a motion for nonsuit, the issue in the case is instructive for the quantum of evidence necessary to establish a prima facie case of liability under
Barker.
In its discussion of
Barker,
the Supreme Court described two alternative tests for establishing whether a product is defectively designed. The second
Barker
test is applicable here. The Supreme Court said: “Under the second prong of
Barker,
the plaintiff must establish a prima facie case of causation. That is, evidence must be adduced which would permit a jury to find that a design feature of the product was a proximate cause of plaintiff’s injury. Once plaintiff has made such a showing, the burden of proof shifts to respondent under the second
Barker
test. ”
(Campbell,
*189
This court in
McGee
v.
Cessna Aircraft Co., supra,
Parallel to this analysis and the second prong of
Barker,
McGee argues failure to comply with F.A.R.’s requiring engine fires be excluded from the cockpit by the firewall for 15 minutes is a design defect which is unreasonably dangerous. The F.A.R.’s set a minimum standard for product safety, and Cessna failed to meet this standard. (See discussion
Turner
v.
General Motors Corporation
(Tex.Civ.App. 1974)
Endicott
v.
Nissan Motor Corp., supra,
The plaintiff in
Endicott
also attempted to invoke the doctrine of negligence per se based upon violation of a Vehicle Code. The plaintiff failed in this assertion for two reasons. First, the Vehicle Code section did not specify physical
*190
engineering standards. It simply provided in general terms a seat belt must “ ‘prevent or materially reduce the movement of the person using the same in the event of collision or upset of the vehicle.’”
(Endicott,
Both doctrines, negligence per se based on viоlation of a safety regulation and strict liability for defective products, shift the burden of proof onto defendants for reasons rooted in sound economic and public policy. (See
McGee
v.
Cessna Aircraft Company, supra,
III
McGee next argues the trial court erred in using BAJI No. 3.75 instead of BAJI No. 3.76. The instruction given by the trial court reads: “A proximate cause of an injury is a cause which, in natural and continuous sequence, produces the injury, and without which the injury would.not have occurred.” McGee urges this causation instruction: “a legal cause of an injury is a cause which is a substantial factor in bringing about the injury. ” In legal jargon BAJI 3.75 describes “but for” causation; BAJI 3.76 describes “substantial factor” causation.
McGee relies upon
Fraijo
v.
Hartland Hospital
(1979)
In
Self v. General Motors Corp., supra,
Our court considered a similar issue in
Vecchione
v.
Carlin
(1980)
This instruction is designed to be used where the injury would have resulted from either of two causes. It is based on the holding in
Thomsen
v.
Rexall Drug & Chemical Co.
(1965)
Neither Vecchione nor McGee are cases involving concurrent causes. In Vecchione the death was caused either by the hospital’s negligence or by prenatal and birth injuries. In this case it is conceded the injuries were caused by the post-crash fire. After this concession, the analysis becomes more complicated. In this case, the fire could have resulted either from the severity of the impact or the design of the aircraft. The principle announced in Thomsen and reiterated in Vecchione is “where there are concurrent causes, our law provides one cannot escape responsibility for his negligence on the ground that identical harm would have occurred without it.” (Vecchione, at p. 359.)
We find the requested “substantial factor” instruction should have been given under the rules announced in Self v. General Motors Corp. Vecchione v. Carlin does not require a different result.
*192 IV
McGee argues FAA investigator Robert Griscom should have been allowed to testify concerning the crashworthiness of the aircraft and the efficacy of the aircraft’s post-impact safety features based on his observations at the scene of the accident. The trial court excluded this testimony as cumulative under Evidence Code section 352 and because according to federal regulation, federal aviation investigators are not permitted to give opinion testimony as experts. The proffered testimony included observations at the scene of the аccident, standard calculations based upon those observations, and analysis of the post-crash fire and protection of the occupants afforded by the aircraft.
Although the trial court has wide latitude in determining whether evidence is cumulative
(People
v.
Albert
(1960)
Cessna argues Griscom was precluded from giving opinion testimony by federal regulation. (14 C.F.R. §§ 9.11, 9.13.) In fact Griscom cited these regulations when he refused to answer defense counsel’s request for a conclusion. The regulations permit an FAA employee to testify but prohibit the employee from offering expert or opinion testimony. FAA employees may “testify relative to that which they observed at accident scene and manner in which they conducted their investigation.”
(Keen
v.
Detroit Diesel Allison
(10th Cir. 1978)
We conclude Griscom should bе allowed to testify on matters relating to crashworthiness based on his personal observations at the scene of the accident, the manner in which he conducted his investigation and standard calculations based upon those observations. We trust opposing counsel to object and the trial court to limit his testimony if his testimony ranges into opinions and conclusions which he is not permitted to give under the federal aviation regulations or which exceed his expertise.

McGee finally contends statements made by passenger witness Dorothy Watts Fickeisen to the FAA were improperly admitted. Fickeisen testified on direct examination:
*193 “Q. During this flight, did you become aware of any significant turbulence involving the flight?
“A. No.”
McGee’s counsel objected when, in cross-examination to impeach Fickeisen, defendant’s counsel read a statement given by Fickeisen to the FAA:
“Q. Reading the very brief statement, there, Mrs. Fickeisen:
“ ‘We were on take off at Warner Hot Springs. On turn-out of pattern we hit downdrafts and could not gain any altitude.’
“Was that a statement that you gave to the FAA?
“A. I gave that statement, but I later said that my terminology of downdrafts was not correct.
“Q. And when you later said that, to whom did you say that?
“A. When it was brought up in [the first] trial.
“Q. And your testimony here today was that you don’t recall any particular turbulence in thе flight, isn’t that true?
“A. Yes.
“Q. That’s your present recollection, you don’t recall any particular turbulence.
“A. That’s correct.
“Q. Such as might be encountered by a light plane if there are gusts or severe weather conditions or even mild weather conditions?
“A. Yes.
“Q. The flight seemed more or less smooth to you?
“A. Yes.”
McGee argues that “turbulence” and “downdrafts” are terms of art and because they do not mean the same thing, they are not inconsistent and therefore the statement is inadmissible. Either term could reflect the witness’ *194 perception of a drop in altitude and therefore the statement would appear to be inconsistent to a jury. However, counsel offered Fickeisen an opportunity to explain the inconsistency which she did. (Evid. Code, §§ 1235,770.) Fickeisen stated:
“A. Like I said before, I have several times said that that terminology was not what I would use now.” Plaintiffs counsel queried:
“Q. What terminology?
“A. ‘Downdrafts.’
“Q. What would you use now?
“A. I would just say that we were not gaining altitude.” The quality of her explanation merely goes to the weight afforded the impeaching testimony. It was not error to permit the testimony.
The judgment is reversed for the reasons set forth in II and HI.
Brown (Gerald), P. J., and Cologne, J., concurred.
A petition for a rehearing was denied February 7, 1983, and respondent’s petition for a hearing by the Supreme Court was denied April 13, 1983. Richardson, J., was of the opinion that thе petition should be granted.
Notes
McGee
v.
Cessna Aircraft Co.
(1978)
The instructor remains pilot in command even when the student has physical control over the aircraft. The aircraft has dual controls.
McGee’s burn doctor testified a first degree burn is similar to a sunburn. A second degree burn is more severe, while a third degree burn affects the entire skin thickness. A fourth degree bum indicates the skin is burned away and the underlying body structure is affected.
Federal Aviation Regulation 23.1191, Firewalls, in force and effect at the time the subject aircraft was designed provided in part as follows: “(a) Each engine, . . . must be isolated from the rest of the airplane by firewalls, shrouds, or equivalent means, [¶] (b) Each firewall or shroud must be constructed so that no hazardous quantity of liquid, gas, or flame can pass from the engine compartment to other parts of the airplane, [¶] (c) Each opening in the firewall or shroud must be sealed with closefitting, fireproof grommets, bushings, or firewall fittings. . . . [¶] (g) Firewall materials and fittings must resist flame penetration for at least fifteen minutes. ” (Italics added.)
Federal Aviation Regulation 23.561, in force and effect at the time the subject aircraft was designed provided in part as follows: “(a) The airplane, although it may be damaged in emergency landing conditions, must bе designed as prescribed in this section to protect each occupant under those conditions. [¶] (b) The structure must be designed to give each occupant every reasonable chance of escaping serious injury in a minor crash landing when—(1) proper use is made of belts or harnesses provided for in the design; and, (2) the occupant experiences the ultimate inertia forces shown in the following table: Ultimate Inertia Forces. Upward—3.Og. Forward—9.Og. Sideward— 1.5g.”
The proffered instruction: “If you find that the defendant Cessna Aircraft Company violated one or more of the regulations contained in part 23 of the Federal Aviation Regulations previously read to you, the burden of proof on the issue of proximate cause shifts from the plaintiff to the defendant. That is, the defendant Cessna Aircraft Company has the burden of proving that the plaintiffs injuries and damages were not the proximate result of any violation of the Federal Aviation Regulations.”
This instruction reads: “Where two causes combine to bring about an injury and either one of them operating alone would have been sufficient to cause the injury, either cause is considered to be a [proximate] [legal] cause of the injury if it is a material element and a substantial factor in bringing it about, even though the result would have occurred without it.”
