NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Require that all Boeing 737 airplanes operated under 14 Code of Federal Regulations parts 121 or 125 that are not equipped with a flight data acquisition unit be equipped, at the earliest time practicable but no later than August 1, 2001, with a flight data recorder system that records, at a minimum, the parameters required by FAA final rules 121.344 and 125.226, dated 7/17/97, applicable to that airplane plus the following parameters: pitch trim; trailing edge and leading edge flaps; thrust reverser position (each engine); yaw damper command; yaw damper on/off discrete; standby rudder on/off discrete; and control wheel, control column, and rudder pedal forces (with yaw damper command; yaw damper on/off discrete; and control wheel, control column, and rudder pedal forces sampled at a minimum rate of twice per second). (Supersedes Safety Recommendation A-96-107, A-96-109, A-96-112, and A-96-113)
In plain language (FlightFinder summary)
The Federal Aviation Administration must require that all Boeing 737 airplanes operated under 14 CFR parts 121 or 125 without a flight data acquisition unit be fitted with a flight data recorder system by August 1, 2001. The recorder must capture at least the parameters specified in FAA final rules 121.344 and 125.226 (dated 7/17/97) plus additional parameters including pitch trim, flap positions, thrust reverser position, yaw damper commands and status, standby rudder status, and control forces sampled at least twice per second.
