Featured Maps: Uncontained Engined Failures (8 November 2010)

Last week's uncontained engine failure of a Rolls-Royce Trent 892 engine on an Airbus A380 operating Qantas Airways flight 32 SIN-SYD has led to an assortment of comments in the press about the rarity of such events. While uncommon, uncontained engine failures do occur more frequentlty than one might expect. In letters A-98-125 and -126, dated 3 December 1998, the National Transportation Safety Board (NTSB) cited (in footnote 17) the following numbers of uncontained low-pressure turbine (LPT) failures:

Those statistics don't include Rolls-Royce engines nor do they include high-pressure turbine (HPT) or compressor or fan portions of engines.

Combing personal correspondence easily produced a list (hardly comprehensive) of uncontained failures of engines from various manufacturers, which form today's featured map:
