General Maintenance Action
Aircraft; MEL; Procedure
Aircraft was hit by a runaway baggage cart and ferried to ZZZ1. The special flight permit was written to operate unpressurized and in non RVSM airspace but the aircraft was never downgraded to NON-RVSM.GMM X.XX.X under the Maintenance Control department; Note: If discrepancy prevents CAT II or RVSM operation; apply the applicable [autoland minimum] and/or RVSM MELs.I talked to the mechanics who returned from the road trip about why the aircraft wasn't downgraded to NON-RVSM and they told me Maintenance Control didn't say anything about that.Just to be clear; the aircraft did not operate in RVSM airspace; it was just never downgraded to NON-RVSM. The MELs should have been issued by Maintenance Control and told the mechanics to enter it in the log book and downgrade the aircraft.
EMB-175 pilot reported that aircraft was not downgraded correctly after ground damage to the RVSM area.
