A Cargologic Air Boeing 747-400, registration G-CLBA performing flight CLU-473 from Frankfurt/Main to Munich (Germany), was on approach to Munich's runway 26R when a flap track fairing from the right hand wing separated from the aircraft and fell onto a field at Wartenberg about 7nm short of the runway threshold. The aircraft continued for a safe landing on runway 26R and taxied to the apron, where it was discovered the part was missing. There were no injuries, aircraft and field sustained minor damage.

The occurrence aircraft is still on the ground in Munich about 11 hours after landing.

The part was recovered by local police and is being handed over to Germany's BFU.

A ground observer reported the aircraft was missing a flap track fairing between the right hand engines.

On Oct 5th 2017 the BFU released their factual report reporting the aircraft was about 12km before touchdown at 146 KIAS when the crew selected the flaps to 30 degrees and heard some sound. The aircraft continued for a landing without further incident.

The BFU wrote:

After the airplane had reached the parking position at the apron it was determined that the track hinge fairing of the outer flap drive (No 8) on the right wing was missing. Some brackets and connection rods in the vicinity of the flap track and carriage were fractured or bent (see Appendix Image 1). The aft flap was slightly dented on the lower surface in the area of the right, outer flap drive.

In the vicinity of the township Wartenberg (about 2 km south-west) a fairing, originating from an aircraft, was found on a meadow (see Appendix Image 2). It was located about 12 km east of the threshold 26R in the area of the approach centreline. After the salvage operation and transport to Munich Airport it was confirmed that the fairing was indeed the one missing.

The two bolt lead-throughs of the front mounting points (see Appendix Image 3) showed scratching and friction traces on the flap track and carriage and the fairing side (see Appendix Images 4 and 5). Both bolt connections were missing. The bolts were neither found in the periphery of the flap drive nor at the meadow.

On the aft fairing extension mechanism the support fitting had been turned by almost 180° and ripped. The bolt receptacle had forcibly been torn out (see Appendix Image 6). The bolt was found in the support fitting on the wing. The bolt receptacle of the adjustable rod had been torn off the support fitting of the wing. This bolt was found in the fixing eyelet of the adjustable rod.
