Plain English Summary

1/10 complexity

This is an Airworthiness Directive (a mandatory safety order issued by the aviation regulator) for owners and operators of Pilatus Britten-Norman BN-2 Series aircraft (twin-engine utility planes commonly known as Islanders).

What you must do:

Modify the engine oil return pipes on your aircraft according to the technical instructions in Britten Norman Service Bulletin BN-2/SB.40 Issue 2.
Complete this work within 100 hours of flight time after 26 February 1971.

Why it matters: This directive fixes a specific safety defect in the engine oil return system. If not addressed, faulty oil return pipes could cause engine oil starvation, potentially leading to engine failure and loss of the aircraft.

Who it affects: Anyone who owns, operates, or maintains BN-2 series aircraft in Australia.
