S92, en-route, southwest of Stavanger Norway, 2020

Summary

On 20 October 2020, the crew of a Sikorsky S92A en route overwater to an offshore oilfield southwest of Stavanger received an engine 1 fire warning. They responded by shutting down the engine, deploying both fire extinguishing bottles, and eventually declaring a MAYDAY without taking all recommended steps to confirm an actual fire existed. They were aware that false engine fire warnings on this helicopter type had become a fairly regular occurrence, and when the warning persisted, they restarted the engine which ran normally. The flight was completed and made an uneventful landing on a platform close to the originally planned destination.

Description

On 20 October 2020, a Sikorsky S92A (LN-OMI) operated by Bristow Norway on a North Sea offshore passenger flight from Stavanger to the Ekofisk Kilo offshore oil and gas platform as BHL203 was approximately an hour into the flight in day visual conditions (VMC) when a left engine fire warning occurred. There were no secondary indications that a fire had occurred, but the engine was shut down and both fire bottles were discharged. However, the warning continued. Since the Ekofisk platforms were nearer than the nearest airport (Stavanger) it was decided to continue there. A MAYDAY was eventually declared, but since the warning had continued the crew believed it was most likely false. The engine was successfully restarted and the flight completed without further event.
