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 currently have a flight data acquisition unit be equipped, by July 31, 2000, 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 is asked to mandate that by July 31, 2000, all Boeing 737 aircraft operating under 14 CFR Parts 121 or 125 and already having a flight data acquisition unit be fitted with a flight data recorder system. This system must record the minimum parameters from FAA final rules 121.344 and 125.226 (dated 7/17/97) plus additional parameters including pitch trim, flap positions, thrust reverser positions, yaw damper commands and status, standby rudder status, and control forces, with some parameters sampled at least twice per second. This recommendation replaces earlier Safety Recommendations A-96-107, A-96-109, A-96-112, and A-96-113.
