Legal Interpretations
Mirkin-FlyRight 2018
Summary
The Question
Can simulator instructors and check airmen meet the two-flight-segment requirement of 14 CFR 135.337(f) and 14 CFR 135.338(f) by flying a light piston twin?
Background
FlyRight, a part 142 training center with programs for BE-200, BE-300, CE-208, DHC-8-100, and DHC-8-300 aircraft, proposed having its simulator instructors and check airmen fly their 12-month two-segment requirement in a light piston twin, and asked the FAA to revisit its 2014 interpretation.
The FAA’s Interpretation
No. The two flight segments must be flown in the type of aircraft involved; if the aircraft has no type rating, the class and then the category must be the same, because the requirement is for experience in a similar aircraft. The FAA declined to change its May 22, 2014, interpretation, noting the 1996 rule added simulator flexibility without relaxing the experience requirements.

Re: Requirements for instructor (simulator) and check airmen (simulator) under
14 C.F.R. §§ 135.337(f) and 135.338(f).
Dear Mr. Mirkin,
This letter responds to your May 4, 2018 request for a legal interpretation of 14 C.F.R. §§ 135.337(±) and 135.338(±), which prescribe qualifications for check airman and flight instructors who perform checking or instructor functions for a particular aircraft in a flight simulator, flight training device, or both. You represented that FlyRight is an FAA-certificated part 142 training center providing FAA-approved training programs for BE-200, BE-300, CE-208, DHC-8-100, and DHC-8-300 type aircraft. First, you asked if FlyRight would fulfill the requirements of§§ 135.337(±) and 135.338(±) if its instructors (simulator) and check airmen (simulator) flew their 12-month two-segment requirements referenced in those regulations in a light piston twin engine. Second, you requested that this office revisit its May 22, 2014, legal interpretation of 14 C.F.R. §§ 135.337(±) and 135.338(±). See Legal Interpretation to Brian Sutch, from Mark W. Bury, Assistant Chief Counsel for International Law, Legislation and Regulations (May 22, 2014). Section 135.337(±) provides in pertinent part:
A check airman (simulator) must accomplish the following:
(1) Fly at least two flight segments as a required crewrnember for the type, class, or category aircraft involved within the 12-month preceding the performance of any check airman duty in a flight simulator; or (2) Satisfactorily complete an approved line observation program .... In addition, Section 135.338(±) provides that:
A flight instructor (simulator) must accomplish the following--

(1) Fly at least two flight segments as a required crewmember for the type, class, or category aircraft involved within the 12-month period preceding the performance of any flight instructor duty in a flight simulator; or (2) Satisfactorily complete an approved line-observation program .... The answer to your question is no. A check airman (simulator) and flight instructor (simulator) must fly at least two flight segments for the type aircraft involved within the 12-month period preceding the performance to comply with§ 135.337(£). As stated in the 2014 legal interpretation, recency of experience in a light piston engine would not satisfy the recency requirements for serving as a check airman or instructor in an aircraft of a different type, class, or category aircraft. Because the purpose of the requirements is for experience in a similar aircraft, the aircraft type must be the same. If the aircraft does not have a type rating, then the class and category, in that order, must be the same. As stated in the 1996 final rule, these paragraphs were intended to add flexibility to acquire the experience in a flight simulator but not to relax the existing requirements for experience in simulator aircraft. 61 Fed. Reg. 30734, 30735 (June 17, 1996). The FAA has considered your request for reconsideration. However, the 2014 legal interpretation was the appropriate interpretation of§§ 135.337(f) and 135.338(£). As stated in the 2014 interpretation, you may consult with your local FSDO or CMO for guidance on whether meeting the requirement in one aircraft may fulfill the requirement in another aircraft.
This response has been coordinated with the Air Transportation Division of Flight Standards Service. If you need further assistance, please contact our office at (202) 267- 7728.

Lorelei D. Peter
