A Boeing 747 undertakes its major service every 26,000 flying hours (about every 4-5 years). The process takes around 56,000 man-hours (around 6 weeks). The cost of the service in parts and labor alone is $4.5 – $6 million. The cost of purchasing a brand new 747-400 is around $234.0 – $266.5 million USD.

The Boeing 747-400 is one of the world’s largest passenger jet liners at 70m long with a 60m-wing span. Its tail stands 19.5m tall and it holds 427 passengers in a typical “tri-class” configuration. With a fuel capacity of 230,000 litres of jet fuel, the aircraft has a range of 13,340km enabling flights between Sydney and San Francisco non-stop.
The maximum take-off weight of the aircraft is 396,890kg. Each engine produces 27,240kg thrust (approx. 55,000hp) on take-off, which produces enough suction into the intake to ingest an adult male from 30 metres.
