Suspected Unapproved Parts
Parts manufactured by MTU for Rolls Royce 250 series engines
Parts manufactured by MTU between 1997 and 1985 for model 750 - MTU - C20B engines built by MTU under a licence from Rolls-Royce (Allison at the time)
To alert maintenance organisations and operators that the FAA does not approve certain MTU manufactured parts for use in commercial aircraft.
Although MTU manufactured certain critical parts from Rolls-Royce drawings, MTU was not an FAA approved manufacturing facility, nor were the facilities covered under the Rolls-Royce quality control system. Therefore, due to certification issues, and the fact that these parts were sold for military use, the FAA does not approve these parts for use in commercial aircraft.
The un-approved parts are identified in the Rolls-Royce Commercial Service Letters listed below.
Operators and maintenance organisations use the lists of part numbers and manufacturing codes provided in the following Commercial Service Letters to detect and eliminate all parts that are not eligible for installation in Rolls-Royce Model 250 commercially operated engines.
