Plain English Summary

2/10 complexity

This directive forces owners/operators of SAAB SF340A aeroplanes (serials 103–139) to inspect—and, if needed, repair or replace—specified composite parts per SAAB SB SF340-51-006. Inspections are required at the next A- or E-check after 29 March 1989 and after defined heavy landings or turbulence, recurring until an Authority‑approved repair/replacement scheme is implemented.

The aim is to mitigate delamination (worsened by water intrusion) that could impair structural integrity; operators bear the inspection, repair, parts and downtime costs.
