The Teledyne CAE J402 is an American small turbojet engine. Several variants have been developed to power unmanned air vehicles such as missiles and target drones. Developed in the 1970s for the Harpoon anti-ship missile, the J402 was the first jet engine to be designed as a "wooden round", meaning that the engine had to be able to sit for long periods without maintenance or inspection and ...
[3] [4] The MRBR is based on the analysis performed using ATA "MSG-3 Operator/Manufacturer Scheduled Maintenance Development" document (MSG-3 is for Maintenance Steering Group – 3rd Task Force). [4] The MRBR is an approved set of aircraft initial maintenance requirements as prescribed by the Appendix H to para. 25.1529 of 14 CFR part 25 ...
In the 1930s Walter also made Bristol Jupiter, Mercury and Pegasus engines under licence, and then created its own in-line inverted air-cooled four- and six-cylinder engines, and in 1936 an air-cooled inverted V12. Walter aircraft engines were used by the air forces of 13 countries before World War II. [1]
In 2017, of the $70 billion spent by airlines on maintenance, repair and overhaul (MRO), 31% were for engines, 27% for components, 24% for line maintenance, 10% for modifications and 8% for the airframe; 70% were for mature airliners (Airbus A320 and A330, Boeing 777 and 737NG), 23% were for “sunset” aircraft (McDonnell Douglas MD-80 ...
The McDonnell Aircraft Corporation was an American aerospace manufacturer based in St. Louis, Missouri.The company was founded on July 6, 1939, by James Smith McDonnell, and was best known for its military fighters, including the F-4 Phantom II, and crewed spacecraft including the Mercury capsule and Gemini capsule.
A lack of standardization and training in both aircraft maintenance and flight operations was cited as a causal factor in a large percentage of mishaps.
