What happened
On February 21, 2011, a Royal Air Maroc Boeing 737-800, operating under registration CN-ROR, was approximately 20 miles from Casablanca Mohammed V airport when the crew reported an automatic in-flight shutdown of the right-hand CFM56-7 engine. The crew attempted to relight the engine, but the attempt was unsuccessful. The aircraft subsequently landed uneventfully using only one engine. There were no injuries resulting from the event.
The investigation
A post-flight inspection identified a loose v-band clamp located in a hot air bleed tube near the Electronic Engine Controller (EEC). Records indicated that maintenance work had been performed in the vicinity of the EEC on the day prior to the incident.
