US Airways says it is conducting a thorough review of a Boeing 767 that experienced two separate incidents of odours circulating in the aircraft cabin.
News outlets are reporting that in the latest episode, which took place on 16 March, engine exhaust made its way into the cabin on a flight from Charlotte to Montego Bay, Jamaica before takeoff.
While several reports indicate the US FAA is attributing the incident to faulty door seals, a US Airways spokesman clarifies that when the aircraft is not pressurised, the seals are not airtight.
That episode follows incidents in late 2009 involving strange cabin smells on the same aircraft. The carrier's spokesman says those incidents were linked to engine oil circulating in the aircraft's bleed air system.
In a US Airways employee update issued prior to the latest episode, the carrier says the 767 was taken out of service on 16 January following reports of odours in the cabin.
The carrier says it fixed the issue and put the aircraft back into service on 21 January, and it had operated without incident during that time.
