|Date issued:||09 October 2007|
|Safety action status:||Closed - Action Taken|
|Background:||Why this Recommendation was developed|
The Australian Transport Safety Bureau recommends that Pratt & Whitney Canada, in conjunction with the aircraft and starter-generator manufacturers, incorporate a suitable inspection of the starter generator gear shaft input coupling spline for any evidence of Electrical Discharge Damage (EDD), if the starter generator is replaced in order to rectify a reported engine starting or electrical generation defect.
|Response from:||Pratt and Whitney Canada response|
Pratt and Whitney Canada response Pratt and Whitney responded to this proposed safety recommendation (draft recommendation B) in the ATSB draft report by stating:
The ATSB accepts P&WC's response and agrees that the starter-generator external spline is the most practical and effective method to determine if there has been an EDD event. As such the ATSB has reworded and now formally issues safety recommendation R20070016.
