A Boeing 747-400 aircraft operated by British Airways, was conducting flight BA212 from Boston/General Edward Lawrence Logan Intl (KBOS), MA to London/Heathrow (EGLL), UK.
During cruise fight approximately 100 nm north of Greater Moncton/Romeo Leblanc Intl (CYQM), NB, the flight crew reported fumes in the cockpit, declared a PAN PAN, and requested a return to KBOS. The flight crew donned their oxygen masks for the duration of the flight. The fumes only became noticeable in the cabin toward the end of the flight; the passenger masks were not used.
The aircraft landed without further incident.
Extensive inspections and function checks were carried out on a number of systems/components
on the aircraft. The fumes were found to have originated from a defect or contamination within air conditioning pack number 2. The pack has been locked out, and the aircraft returned to EGLL using MEL 21-51-01 on January 23. The pack will be inspected within the 10 day period allowable for this defect in order to determine the exact cause of the issue.
