Report on aviation incident 120 NM southwest of Stavanger Airport Sola, Norway, on 20 October 2020 involving Sikorsky S-92A, LN-OMI, operated by Bristow Norway AS
Aviation report 2025/05
On Tuesday October 20, 2020, Sikorsky Aircraft Corporation S-92A LN-OMI, operated by Bristow Norway AS, was en route from Stavanger Airport Sola (ENZV) to the Ekofisk Kilo (ENXK) oil and gas platform. Just under an hour into the flight, a fire warning for engine 1 was triggered. The crew decided to stop the engine and used the two fire extinguishers that were available. The fire alarm continued, but since they did not register any other indications of fire, they concluded that the alarm was false. They therefore restarted the engine and continued towards Ekofisk oil and gass field where they landed at Ekofisk Lima.
After landing, the engine and engine compartment were inspected, and it was ascertained that there had been no fire.
There have been a number of false engine fire warnings on S-92 helicopters. However, the warnings have normally only lasted a short time. The NSIA believes that false warnings poses a serious problem, particularly because false warnings reduce confidence in the fire warning system. The incident touches on several issues concerning false fire warnings and how they are dealt with.
