Incident at Winnipeg, MB


1999-09-28: SGK 300, a Cessna 402 with 2 crew and one passenger, was enroute from Winnipeg (YWG) to Milwaukee and was about 55 miles south of YWG when the crew reported a dual alternator failure. The Captain decided to return and turned off all unnecessary electrics to conserve battery power. The crew lowered the gear manually and did a fly-by of the Tower to confirm gear down. The a/c landed uneventfully. The company is presently examining the a/c to determine the cause of the failure. OPI - Maintenance and Manufacturing UPDATE M. & M. reported that the R/H voltage regulator failed internally. Both L/H & R/H regulators were removed for testing and repairs. Both alternator brushes checked, nothing abnormal found. Regulators adjusted and paralleled on the bench. R/H alternator replaced with serviceable alternator. Aircraft ground run serviceable.
