A Jetconnect Boeing 737-800, registration ZK-ZQC performing flight QF-37 from Melbourne,VI (Australia) to Wellington (New Zealand), was climbing out of Melbourne when the crew retracted the gear and received indication all gear had fully retracted and locked up. The crew subsequently moved the gear lever to off permitting the gear hydraulic system to depressurize, which caused the right main gear to fall into its down position. The crew selected the gear lever into the up position, the right main gear retracted again and remained in the up position. The crew continued the flight to Wellington for a safe landing.

New Zealand's TAIC reported within the investigation into another occurrence, see Report: Jetconnect B738 at Sydney and Auckland on Jun 7th 2013, rag damages stab trim system, that maintenance in Wellington found a rag had been wrapped around the right main gear's uplock assembly. It was established that a maintenance engineer at the Qantas maintenance facility in Melbourne had used the rag to protect his head against an accidental head strike at the uplock gear assembly, but had forgotten to remove the rag after the work had been completed.

The TAIC reported that no investigation had been opened into the occurrence, the occurrence however helped to identify an issue within the investigation into the other occurrence. The TAIC released a key lesson however:

All personnel must take care not to leave anything behind inside an aircraft after completing maintenance or cleaning tasks, especially in areas or near systems critical to flight safety.
