Shell Brunei S92A landed off the air field, onshore, due to another MGB hot warning with no oil pressure, they may have had another rash of warning, but I don't know, with some smoke/mist in the cockpit/cabin. Well done to the crew... All S92 in Brunei Shell grounded.
Sikorsky issued this..
Sikorsky Aircraft has been advised of an incident in which an S-92 experienced a loss of main gearbox oil
pressure and increased main gearbox oil temperature. As a result of a previous gearbox investigation
following a similar incident, Sikorsky issued Alert Service Bulletin (ASB) 92-63-008 to inspect the main
gearbox oil dipstick tube for proper length.
Sikorsky Aircraft is working with the customer to determine the root cause of both these events. If any
additional fleet actions are deemed necessary, they will be disseminated to the affected portion of the fleet
by an appropriate Alert Service Bulletin.
If you have any questions, please contact your Field Service Representative or Customer Service
Engineering at 1-800-WINGED S or (203) 386-3001.
Very truly yours
SIKORSKY AIRCRAFT CORPORATION
