Plain English Summary

2/10 complexity

This directive orders a safety inspection of specific aviation life jackets. It applies only to Beaufort (Airsea) MK.8E and MK.8E(W) life jackets fitted with Knapp Monarch operating mechanisms (part numbers KN-A138 or KN-A135).

The safety problem: Tests found that the thread where the gas cylinder screws in is too short. This means the cylinder might not seal properly or get punctured when the mechanism is activated, potentially preventing the life jacket from inflating during an emergency.

What must be done: Owners or operators must have these life jackets inspected within 12 months after 30 September 1983. The inspection must follow either:

Beaufort Service Bulletin No. 043; or
A procedure approved by the Secretary (the senior government official responsible for aviation safety).

AD/EMY/19 Life Jackets - Inspection 9/83

Applicability: Beaufort (Airsea) Equipment Life Jackets MK.8E and MK.8E(W) fitted with either a plastic or die-cast Knapp Monarch operating mechanism P/Nos. KN-A138 and KN- A135.

Document: 1. Beaufort SB No. 043; or

An inspection procedure approved by the Secretary. Compliance: Within 12 months after 30th September 1983.

Background: Compatibility tests with both square-end and tapered-end cylinders have established that the thread in the cylinder aperture is too short and will not permit the end of the cylinder to mate with the face seal. This defect is potentially serious as it could result in the cylinder not being punctured by the firing pin when the mechanism is actuated.
