This airworthiness directive requires operators of HC‑B3TN‑5/T10282 (H) Hartzell propellers on specified Swearingen SA226/SA227 aircraft with listed Garrett TPE‑331 engines to perform dye‑penetrant or other CASA‑approved non‑destructive inspections of the outer 60 cm of each blade (face and back) to detect cracks, following Hartzell SB 146A. It took effect on 5 September 1991 and requires repeating the inspection at intervals not exceeding 100 flight hours; operators bear the inspection cost and must follow the CASA AD and the manufacturer’s service bulletin.

Applicability: All HC-B3TN-5 ( ) ( )/T10282 (H) (B) propeller models installed on Swearingen SA226T, SA226T(B), SA22AT, SA226TC Metro aircraft with Garrett Engine model TPE-331-3U-303G, TPE-331-3UW-303G, TPE-331-10UA-501G or -511G.

Requirement: Action in accordance with Hartzell SB 146A.

Carry out a dye penetrant or other Departmentally approved non-destructive inspection to the outer 60 cm area of the subject blades both back and face. Inspect for signs of cracking, propagating from the trailing edge forward.

Compliance: The compliance date of the previous issue of this Directive (AD/PHZL/49 Amdt 3) was 30 June 1986. This Directive is effective from 5 September 1991, and thereafter at intervals not exceeding 100 hours Time in Service.

Background: This Directive has been amended to list propeller, engine and aircraft combinations affected which have now been identified in the propeller manufacturer’s SB. The inspection has been changed to conform with the requirement of the SB. Soft alloy has been dropped from the heading since the manufacturer has cleared these blades of fault. This AD is raised to incorporate the propeller insp’n in the aircraft series.
