Beechcraft: B300; Cracked Windscreen; ATA 5610
A repair station submission reads, “At an altitude of 17,000 feet (and an outside temperature of minus 6 degrees Celsius) the right windshield cracked (about 2 inches outboard of the center post) from the top to the bottom in the outer pane. The aircraft returned to the departing airport without any problems (and) the windshield (P/N 101-384025-24) was replaced. There was no known cause for this part to have cracked.” (Reference also the following Alerts: December 2004, for two such reports; January 2005, for another. The full part number returns 12 such reports from the FAA Service Difficulty Reporting System (SDRS) database. Truncating this number from the right one digit at a time for successive searches yields the following results, almost all within the 5610 ATA code: -1 returns, 113 entries since 1998; -2 returns, 209 since 1995; -3 returns, 218 since 1995; -4 returns, 229 since 1995; -5 begins mixing codes.)
