PDA01-5: Dash 8 Forward Butt Plates, Lower Engine Cowl
CHT has done over 89 major repairs to the lower engine cowls on the Dash 8. Many of these repairs include changing the fwd butt plates. Invariably, the pilot holes of OEM replacement butt plates do not line up with the holes at their intended attachment point. CHT holds a PDA (equivalent to a PMA in the US) to manufacture these parts without the predrilled pilot holes for the attachment rivets or the locating pin. These parts can, therefore be matched drilled upon installation without the problem of elongating predrilled holes or redrilling completely new holes. The parts do include the large slot and smaller aft slot which engages the upper nacelle locating pin. The part numbers are as follows:
