Literature :
20 April 2008 Ilyushin Il-62M CU-T1238 Cubana Flight 201 took off from Santo Domingo (SDQ) on a regular service to Havana (HAV). At 45 nm from SDQ and at an altitude of 25000 feet the no. 2 engine suffered an uncontained failure. Fuel lines to engine no. 1 were compromised and a fire erupted. Also, debris had penetrated the fuselage, causing a decompression. Both engines were shut down and the captain decided to return to Santo Domingo.
An emergency descent was carried out, followed by a safe emergency landing.
DISCLAIMER Above calculations are based on published data, they must be
regarded as indication not as facts.
Calculated performance and weight may not correspond with actual weights
and performances and are assumptions for which no responsibility can be taken.
Calculations are as accurate as possible, they can be fine-tuned when more data
is available, you are welcome to give suggestions and additional information
