Plain English Summary

2/10 complexity

This Airworthiness Directive requires Boeing 727 operators to amend the Aircraft Flight Manual emergency procedure wording: replace the ‘Rapid Depressurisation’ donning instruction with a ‘CABIN ALTITUDE WARNING OR RAPID DEPRESSURISATION’ instruction and specify “Oxygen Masks & Regulators—ON, 100%, ALL.”

It applies to all Model 727 aeroplanes, ties mask donning to the cabin altitude warning horn, may be complied with by inserting the Directive into the AFM, and must be done by 20 June 2003.
