As of March 23, 1999

A-92-58: Develop a broader meteorological aircraft hazard program, to include other airports in or near mountainous terrain, based on the results obtained in the Colorado Springs, Colorado, area.
STATUS: OPEN - UNACCEPTABLE RESPONSE

A-96-108: Revise 14 Code of Federal Regulations (CFR) Section 25.671 to account for the failure or jamming of any flight control surface at its design-limited deflection. Following this revision, reevaluate all transport-category aircraft and ensure compliance with the revised criteria. STATUS: OPEN - AWAIT RESPONSE
STAFF PROPOSED STATUS: CLOSED - RECONSIDERED/SUPERCEDED

A-96-109: Require the Boeing Commercial Airplane Group to develop and install on all new-production 737 airplanes a cockpit indicator system that indicates rudder surface position and movement. For existing 737 airplanes, when implementing the installation of an enhanced-parameter flight data recorder, require the installation of a cockpit indicator system that indicates rudder surface position and movement.
STATUS: OPEN - UNACCEPTABLE RESPONSE
STAFF PROPOSED STATUS: CLOSED - UNACCEPTABLE ACTION/SUPERCEDED

A-96-112: Require the Boeing Commercial Airplane Group to establish appropriate inspection intervals and a service life limit for the B-737 main rudder power control unit.
STATUS: OPEN - UNACCEPTABLE RESPONSE
STAFF PROPOSED STATUS: CLOSED - UNACCEPTABLE ACTION/SUPERCEDED

A-96-113: Require the Boeing Commercial Airplane Group to devise a method to detect a primary or a secondary jammed slide in the B-737 main rudder power control unit servo valve and ensure appropriate communication of the information to mechanics and pilots.
STATUS: OPEN - UNACCEPTABLE RESPONSE
STAFF PROPOSED STATUS: CLOSED - UNACCEPTABLE ACTION/SUPERCEDED

A-96-107: Require the Boeing Commercial Airplane Group, working with other interested parties, to develop immediate operational measures and long-term design changes for the B-737 series airplane to preclude the potential for loss of control from an inadvertent rudder hardover. Once the operational measures and design changes have been developed, issue airworthiness directives to implement these actions.
STATUS: OPEN - UNACCEPTABLE RESPONSE
STAFF PROPOSED STATUS: CLOSED - UNACCEPTABLE ACTION/SUPERCEDED

A-96-120: Require 14 CFR Part 121 and 135 operators to provide training to flightcrews in the recognition of and recovery from unusual attitudes and upset maneuvers, including upsets that occur while the aircraft is being controlled by automatic flight control systems, and unusual attitudes that result from flight control malfunctions and uncommanded flight control surface movements.
STATUS: OPEN - ACCEPTABLE RESPONSE
STAFF PROPOSED STATUS: OPEN - UNACCEPTABLE ACTION

A-97-18: Require the Boeing Commercial Airplane Group to develop operational procedures for B-737 flightcrews that effectively deal with a sudden uncommanded movement of the rudder to the limit of its travel for any given flight condition in the airplane's operational envelope, including specific initial and periodic training in the recognition of and recovery from unusual attitudes and upsets caused by reverse rudder response. Once the procedures are developed, require B-737 operators to provide this training to their pilots.
STATUS: OPEN - UNACCEPTABLE RESPONSE
STAFF PROPOSED STATUS: CLOSED - UNACCEPTABLE ACTION/SUPERCEDED

A-95-25: Require that each Boeing 737 airplane operated under 14 CFR Parts 121 or 125 be equipped, by December 31, 1995, with a flight data recorder system that records, at a minimum, the parameters required by current regulations applicable to that airplane plus the following parameters (recorded at the sampling rates specified in "Proposed Minimum FDR Parameter Requirements for Airplanes in Service"): lateral acceleration; flight control inputs for pitch, roll, and yaw; and primary flight control surface positions for pitch, roll, and yaw.
STATUS: CLOSED - UNACCEPTABLE ACTION

A-95-26: Amend, by December 31 1995, 14 CFR Sections 121.343, 125.225, and 135.152 to require that Boeing 727 airplanes, Lockheed L-1011 airplanes, and all transport-category airplanes operated under 14 CFR Parts 121, 125, or 135, whose type certificate applies to airplanes still in production, be equipped to record on a flight data recorder system, at a minimum, the parameters listed in "Proposed Minimum FDR Parameter Requirements for Airplanes in Service" plus any other parameters required by current regulations applicable to each individual airplane. Specify that the airplanes be so equipped by January 1, 1998, or by the later date when they meet Stage 3 noise requirements but, regardless of Stage 3 compliance status, no later than December 31, 1999."
STATUS: CLOSED - UNACCEPTABLE ACTION

A-95-27: Amend, by December 31, 1995, 14 CFR Sections 121.343, 125.225, and 135.152 to require that all airplanes operated under 14 CFR Parts 121, 125, or 135 (10 seats or larger), for which an original airworthiness certificate is received after December 31, 1996, record the parameters listed in "Proposed FDR Enhancements for Newly Manufactured Airplanes" on a flight data recorder having at least a 25-hour recording capacity.
