NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ISSUE AN AIR CARRIER MAINTENANCE BULLETIN-PART 135, DIRECTING ALL PRINCIPAL MAINTENANCE INSPECTORS (PMI) TO BE ALERT TO SIGNIFICANT DEVIATIONS IN COCKPIT INSTRUMENTATION AND EQUIPMENT INSTALLATIONS OF COMMUTER AIR CARRIERS. THE MAINTENANCE BULLETIN SHOULD PROVIDE GUIDANCE WITH RESPECT TO THE HUMAN ENGINEERING PRINCIPLES WHICH ARE DESIRABLE IN ACHIEVING COCKPIT STANDARDIZATION AND WHICH WOULD TEND TO ELIMINATE PILOT ERRORS IN THE INTERPRETATION OF COCKPIT INSTRUMENTS AND THE OPERATION OF EQUIPMENT. THE BULLETIN SHOULD DIRECT PMIS TO ENCOURAGE COMMUTER OPERATORS TO PROVIDE STANDARDIZATION OF COCKPIT INSTRUMENTATION AND EQUIPMENT IN THEIR AIRPLANE FLEET TO THE GREATEST EXTENT POSSIBLE.
In plain language (FlightFinder summary)
The NTSB asks the FAA to issue an air carrier maintenance bulletin under Part 135, directing all principal maintenance inspectors to watch for significant deviations in cockpit instrumentation and equipment installations at commuter air carriers. The bulletin should include guidance on human engineering principles to promote cockpit standardization and reduce pilot errors, and it should direct inspectors to encourage operators to standardize cockpit instrumentation and equipment as much as possible.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
