I am doing some research regarding the cabin air quality issue and I have come across the BAe service bulletin ISB.21-150 revision 2 from October 10th, 2002. The paper says it's effectiv for all BAe 146 aircraft and it describes the work to be done after an oil fume event. Do these procedures also apply for AVRO RJ aircraft? If yes, is that because of this ISB? If not, why?
The service bulletin will list the serial numbers of the effected airframes. If the service bulletin is a "for sale" service bulletin, a service bulletin that not safety related, the owner/operator of the airframe has to pay the OEM to add the serial number to the effectivity.
However, I would assume that any service bulletin effective on the BAe 146 would have been incorporated during production on the Avro RJ's.
