Plain English Summary

2/10 complexity

The directive mandates immediate replacement of the main landing‑gear down‑lock “universal bolt” on all Boeing 727 models, referencing Boeing Service Bulletin No. 32‑106 for the procedure. It affects operators, owners and maintenance organisations: compliance is compulsory, costs (parts, labour, downtime) fall to the operator, and non‑compliance can ground aircraft or prompt enforcement by CASA.
