Narrative:

 

UPDATE: TSB Report#A14P0183: The Helijet Sikorsky S-76A (C-GHJL) was on a test flight about 7 nm S of CYVR when the number 2 engine (Allison 250-C30S) experienced an uncommanded acceleration. The crew reduced power to the number 2 engine, declared an emergency and returned to CYVR for an uneventful landing. The number 2 engine and N2 governor had been recently replaced because of an 18 October 2014 power-loss event (occurrence number A14P0175) and engine chip light events on 23 and 25 Oct 2014 (occurrence number A14P0179). Following the 29 Oct 2014 uncommanded engine acceleration event, company maintenance replaced the droop compensator amplifier (p/n 76900-01880-106) and inspected the associated wiring.
