Helicopter hovered as mechanic fixed stuck landing gear
The S92 was carrying 19 passengers to a Shetland airport when it occurred.
A helicopter had to hover with its nose in the air to allow a mechanic to release its jammed landing gear at a Scottish airport.
The chopper was carrying 19 passengers between the Magnus oil platform and Scatsta Airport in Shetland when the incident occurred on January 29.
The S92 Sikorsky hovered with its back wheels on the ground while its front landing gear was unstuck.
Nobody was injured, according to a report released by the Air Accidents Investigation Branch (AAIB).
Investigators were unable to determine the cause of the fault but steps have been taken to prevent a similar failure in the future, the AAIB said.
It concluded: "The exact cause of the failure of the nose landing gear to centre the nose wheels during retraction could not be determined.
"However, the operator has taken steps to inform its staff of a potential cause identified in previous cases by the manufacturer.
"The incident has also highlighted a discontinuity in the operator's emergency procedures, which have also been addressed."
