20 I INTRODUCTION
21 Defendants’ pilot expert, Captain Barry Schiffis an ATP-rated pilot (Airline Transport Pilot)
22 with over 28,000 flight hours in 357 different aircraft. His curriculum vitae is attached hereto as
23 Exhibit A. Captain Schiff has experienced wind shear on numerous occasions throughout his career
24 as a pilot. In fact, Captain Schiff has also written an article about wind shear for the AOPA (Aircraft
25 Owners and Pilot Association), entitled “Wind Shear: The Mystery of the Vanishing Airspeed.”
26 Captain Schiff’s article is attached hereto as Exhibit B. Captain Schiff does not seek to opine on
27 wind shear as a meteorologist. Among other things, Captain Schiff will testify as an expert pilot
28 witness concerning encountering wind shear as a pilot and what wind shear can do to an aircraft

EGARDING DEFENDANTS’ EXPERT BARRY SCHIFF
when it encounters such turbulence during flight and Mr. MAGEE’s specific encounter with the
turbulence at the time of the incident. As such, he is more than qualified to testify about STEPHEN
MAGEE’s encounter with turbulence during the flight which forms the basis of this litigation
because his testimony is clearly based on his special knowledge, skill, experience, training, and
education.
IL. BARRY SCHIFF IS QUALIFIED AS AN EXPERT PILOT
WITNESS TO TESTIFY REGARDING WIND SHEAR
Evidence Code section 801 provides, in pertinent part, as follows:
“Ifa witness is testifying as an expert, his testimony in the form of an
10 opinion is limited to such an opinion as is:
il +
12 “(b) Based on matter (including special knowledge, skill, experience,
13 training, and education) perceived by or personally known to the
14 witness or made known to him at or before the hearing whether or not
15 admissible, that is of a type that reasonably may be relied upon by an
16 expert in forming an opinion upon the subject to which his testimony
17 relates...”
18 Captain Barty Schiff will be testifying based upon his special knowledge, skill, experience,
19 training, and education as an ATP-rated pilot with more than 28,000 flight hours of experience. His
20 special knowledge is also demonstrated by authoring an article on wind shear and his experience in
ai encountering wind shear during his career as a pilot.
22 Captain Schiff may rely on the testimony of meteorologists Jim Purpura and Jan Null, both
23 of whom have testified as to the presence of wind shear at the site of the incident. He also may rely
24 on the National Transportation Safety Board’s (“NTSB”) weather study which includes achart based
25 on sounding data which shows the presence of low level wind shear at the Half Moon Bay Airport
26 at the time of the accident.
27 Plaintiffs’ suggestion that a pilot cannot testify as to the presence of wind shear during a
28 specific event, despite the fact that the pilot is not a meteorologist, is meritless. In Roberts v. Trans
-2-
OPPOSITION TO PLAINTIFFS’ MOTION IN LIMINE NO, 5 TO EXCLUDE CERTAIN TESTIMONY
REGARDING DEFENDANTS’ EXPERT BARRY SCHIFF
World Airlines (1964) 225 Cal.App.2d 344, the Court of Appeal held that a pilot who encountered
wind shear could testify about that encounter, and that he believed it was wind shear, and that such
testimony constitutes substantial evidence. The Court of Appeal stated, in pertinent part, as follows:
“Pointing out that Captain Gerow was an expert transport pilot whose
opinion was entitled to weight, defendant puts forth his opinion
testimony of a ‘shear wind’ or ‘jet stream’ as substantial evidence
which the jury, as trier of fact, could have accepted as an explanation
for the accident.”
(Id. at 353.)
10 Similarly, the Court of Appeal in Grotheer v. Escape Adventures, Inc. (2007) 14 Cal.App.5th
11 1283, the Court of Appeal relied upon testimony of the presence of wind shear during an incident
12 from a pilot expert witness:
13 “James Kitchel, Grotheer’s expert who has piloted balloons for over
14 25 years, concluded the cause of the crash landing was Gallagher’s
15 failure to maintain safe control over the ‘delta’ temperature [,J
16 anticipate changing pressure differentials [,] and counterbalance the
17 effects on the rate of descent.’ He disagreed with Gallagher’s false
18 lift theory, opining instead the balloon had likely simply experienced
19 a wind shear.”
20 (Grotheer, supra, 14 Cal.App.Sth at 1291.)
21 In addition to being qualified to testify about piloting encounters with wind shear turbulence,
22 Captain Schiffis permitted under Evidence Code section 801 (b) to rely upon the testimony or other
23 evidence provided by others to reach an opinion about whether Mr. MAGEE encountered wind shear
24 turbulence and whether his reaction
to it was reasonable. As stated above, such other matter Captain
28 Schiff could rely upon would be the testimony of Mr. MAGEE, the testimony of defense
26 meteorologist James Purpura or even plaintiffs’ meteorologist, Ernest Jan Null, who also concluded
a7 the presence of wind shear at the location of the incident. (Deposition of Ernest Jan Null, 26:13-15,
28 Exhibit Cc)

OPPOSITION TO PLAINTIFFS’ MOTION IN LIMINE NO. 5 TO EXCLUDE CERTAIN TESTIMONY
REGARDING DEFENDANTS’ EXPERT BARRY SCHIFF
Il. THERE IS NO AUTHORITY FOR DISQUALIFYING AN
EXPERT WITNESS FOR BELIEVING A LAY WITNESS IS
CREDIBLE
Without citing any specific authority, plaintiffs take the position that Captain Schiff should
be precluded from offering any opinion that he will give the pilot, STEPHEN MAGEE, the benefit
of the doubt and then he tried to climb away but could not. It is not unreasonable to assume that a
pilot would want to avoid a crash which ultimately results in fatal injuries to his wife! Plaintiffs’
contention that Captain Schiff’s opinion of MAGEE as “credible” usurps the providence of the jury
is meritless - MAGEE is going to testify at this trial and the jury is free to reach their own opinion
10 as to his credibility. If Captain Schiff concludes that MAGEE is credible, and the jury does not, then
11 the jury will give less weight to the testimony of Captain Schiff, iL.e., weight, not admissibility.
12 The testimony of Captain Schiff cited in plaintiffs’ MIL No, 5 at page 5 comes from a line
13 of hypothetical questions raised by plaintiffs’ counsel concerning climbing when the aircraft is
a4 sinking (Decl, Montanari, Exhibit B, Schiff deposition, 59:7-16.) Captain Schiff does testify that
15 the pilot did attempt to do a “go around” because he added full power which is “a pretty clear sign
16 that he was attempting to go around.” (Decl. Montanari, Exhibit D, Schiff deposition, 61:13-20.)
17 When questioned why Captain Schiff believed MAGEE added full power, he referenced his
18 deposition testimony. (Decl. Montanari, Exhibit D, Schiff deposition, 61:21-62:2.) Captain Schiff
19 based his opinion on the actual testimony of MAGEE, more than a “benefit of the doubt.”
20 Tv. CONCLUSION
21 Based on the foregoing, the Court is requested to deny plaintiffs’ motion in limine No. 5 in
22 its entirety.
