Plain English Summary

3/10 complexity

This airworthiness directive requires operators of British Aerospace Jetstream Series 3100/3200 aeroplanes fitted with certain Pilkington windscreens to carry out inspections and any follow-up actions in accordance with BAe Mandatory Service Bulletin 56-JA 920843 Revision 1; an initial inspection is due within 300 hours time in service after 31 March 1994 unless already completed. It responds to reported cracking of the PVB windscreen interlayer that can lead to windscreen failure; Amendment 1 broadens applicability to all aircraft and adds repetitive inspections for aircraft with the new-type windscreens, shifting inspection and maintenance duties onto operators.
