Plain English Summary

2/10 complexity

What this does: Orders a mandatory safety fix for specific aircraft oxygen masks to prevent the filter from falling out during use.

Who it affects: Aircraft owners and operators using Scott brand oxygen masks (models 28314, 28315, and 28317) that were manufactured before 8 August 1977.

What must be done: The filter retention system must be modified by following one of these manufacturer instruction documents:

Scott Installation Instruction (October 1977); or
Mitsubishi Service Note 39; or
Piper VSP-8.

Deadline: The work must be completed within 100 hours of flight time after 30 April 1978.

Why it matters: Ensures emergency oxygen masks work properly in an emergency—if the filter dislodges, the mask may fail to deliver oxygen when crew or passengers need it most.
