Plain English Summary

2/10 complexity

This instrument requires that specified Dowty Rotol variable‑pitch propeller blades receive a “pre‑primer” per Dowty Rotol SB No. 61‑157 (Mod. No. (c) VP 1941) before being fitted to an aircraft after their next overhaul completed after 28 February 1966. It applies to blades identified in the external requirement document, obliges maintenance organisations/operators to follow the service bulletin, and shifts material and labour costs to whoever performs the overhaul. The directive delegates scope and technical detail to the cited external documents and is silent on verification/enforcement.
