Action in accordance with Rolls Royce Service Bulletin No. 72-A338 as in force from time to time.

Note:  The words “as in force from time to time” require compliance with the most recent version of the referenced document.

Compliance:

For uninstalled engines: Prior to installation on an aircraft, thereafter at each servicing period when the zone 2 cowling is removed.

Background:

This Directive was previously issued to maintain the requirements of AD/RRT‑V/16.  The requirement follows an incident where the exhaust inner cone was lost due to detachment of a cap nut and stay pin.

This amendment removes reference to Civil Aviation Order (CAO) 106 AD/RRT‑V/16 which is no longer applicable.
