2003-01-16: UPDATE Maintenance and Manufacturing reported that the Cessna 421 remains at the OLds/Didsbury airport. It has not been worked on as yet due to waiting for Insurance Company personnel to document and photograph the damage. The local AMO stated that there were no injuries from the event. The complete R/H front windshield departed the aircraft somewhere between Drumheller and Hannah, AB. He also stated that he has been in contact with Cessna and they have stated that this is the 2nd catastrophic windshield failure in a Cessna 421 that they know of. The aircraft is about 34 years old and has approximately 5,000 hours TSN. The original windshields had 5/16"" glass and have since been upgraded to 3/8"" glass. The AMO stated that he has not had the opportunity to determine if the windshield has been changed or the thickness of glass in the failed one. The cause of failure is unknown at this time. There are some impact marks on the R/H fuselage nose forward of the windshield, but ice fragments are not suspected of causing the failure. He will inspect the surrounding structure after the Insurance Company has finished its documentation. He will then submit an SDR.
2003-01-14: C-GSUQ, a Cessna 421, departed Olds-Didsbury for Winnipeg on an IFR flight plan. At 2225Z, while 10 miles east of Hanna and climbing through 17,400 feet ASL, the pilot reported an 'explosive decompression' and commenced an emergency descent. The pilot then requested clearance to divert to Drumheller. Clearance was provided and the aircraft cancelled IFR at 2230Z, leaving the ACC frequency. At 2240Z another aircraft relayed that C-GSUQ was returning to it's point of departure, Olds/Didsbury, where it arrived at 2307Z. The cause of the decompression is not known.
2003-04-07: UPDATE TSB reported that as the Cessna 421A aircraft, C-GSUQ, was climbing through 17,400 feet on departure for Winnipeg, the right half of the windshield shattered and departed the aircraft, resulting in an explosive decompression. The pilot initiated an immediate emergency descent, and requested clearance to divert to Drumheller. Clearance was provided and C-GSUQ cancelled IFR before leaving the ACC frequency. About ten minutes later another aircraft relayed a message that GSUQ was returning to its departure airport of Olds-Didsbury. There were no injuries, but the aircraft had damage around the windshield frame, instrument panel, and glareshield.
