Plain English Summary

3/10 complexity

This AD requires owners/operators of Fokker F28 aircraft (s/n 11003–11241, 11991–11992) to carry out the work in Fokker Service Bulletin F28/32‑153 by 1 November 1995 (unless already done). It responds to a risk that extreme side‑loads can pull a lock toggle link out of overcentre, allowing main‑gear collapse. CASA enforces the deadline; compliance costs, downtime, and implementation risk fall on the affected operators.

AD/F28/76 Landing Gear Locking Mechanism 3/95

Applicability: All F28 aircraft serial number 11003 through 11241, 11991 and 11992. Requirement: Unless previously carried out action in accordance with Fokker SB F28/32-153.

Note: RLD BLA AD 94-163 (A) refers.

Compliance: By 1 November 1995.

Background: The manufacturer has advised that a Fokker 100 experienced a main undercarriage collapse during landing. Subsequent investigation confirmed that no undercarriage component had failed but extreme inward side-load conditions during the landing caused the lock toggle link to be pulled out of the overcentre position resulting in a main gear collapse.
