Plain English Summary

3/10 complexity

This AD mandates installation of a circuit breaker on the 26 Vac output cable of the AII inverter on specified BAe Jetstream 3100 constructor‑number aircraft, to be done per BAe ASB 24‑A‑JA7672A. Affected operators must complete the work before 26 April 1989; owners/operators bear the cost. The measure corrects the lack of over‑current protection identified by BAe and reduces electrical‑fire/fault risk on the listed aeroplanes.
