NTSB Safety Recommendation — Aviation

Recommendation text

BECAUSE ACCIDENTS INVOLVING LOSS OF CONTROL DURING EMERGENCY PARTIAL PANEL OPERATIONS ARE CHARACTERISTICALLY FATAL AS EVIDENCED BY THE FIVE ACCIDENTS CITED, THE SAFETY BOARD BELIEVES THAT A SPECIAL EFFORT IS WARRANTED TO REDUCE THE NUMBERS OF SUCH ACCIDENTS. THEREFORE, THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: CONDUCT AN ENGINEERING EVALUATION TO DETERMINE THE FAILURE MODE AND DESIGN ADEQUACY OF AIRCRAFT VACUUM PUMPS PRODUCED BY THE AIRBORNE MANUFACTURING COMPANY AND THE EDO-AIRE MANUFACTURING COMPANY.

In plain language (FlightFinder summary)

The Federal Aviation Administration is asked to conduct an engineering evaluation of aircraft vacuum pumps made by Airborne Manufacturing Company and Edo-Aire Manufacturing Company to determine their failure mode and design adequacy, because the National Transportation Safety Board found that accidents involving loss of control during emergency partial panel operations are typically fatal, as shown in five cited accidents.

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.
