Accident: Trigana B733 at Wamena on Sep 13th 2016, hard landing results in main gear collapse
By Simon Hradecky, created Tuesday, Sep 13th 2016 05:20Z, last updated Tuesday, Sep 13th 2016 10:01Z
A Trigana Air Service Boeing 737-300 freighter, registration PK-YSY performing flight IL-7321 from Jayapura to Wamena (Indonesia) with 3 crew and 15.3 tons of cargo (fuel, rice, sugar), landed on Wamena's runway 15 at 07:35L (22:35Z Sep 12th) but touched down very hard in a nose high attitude, left the left main gear behind, the right main gear collapsed, and the aircraft slid on nose gear, belly and both engines to a halt at and partly beyond the right hand edge of the runway. There were no injuries, the aircraft sustained substantial damage.
A ground observer reported, the cloud base was about 150-200 feet, the aerodrome features no instrument approaches and thus is strictly visual approach only. A Trigana Boeing 737-300 landed successfully a few minutes earlier, then PK-YSY was seen breaking out of cloud, correcting to the right and pitching down to descend towards the runway. The aircraft subsequently touched down very hard in a nose high attitude, the left main gear separated from the airframe, the right main gear collapsed, and the aircraft skidded on nose gear, both engines and the belly to a halt right of the right hand edge of the runway past the new apron. The airport is currently closed.
Indonesia's Ministry of Transport reported flight TGN-7321/IL-7321, carrying 15,353 kg of freight consisting of drums of Diesel as well as sugar, rice and other goods, was involved in an accident at Wamena at 07:35L, when the aircraft slid to a halt at the right hand side of the runway. There were no injuries. The condition of the runway surface is being assessed, the accident is being investigated by Indonesia's NTSC/KNKT.

AVHerald è una fonte molto attendibile, ma in questo caso noto che l'accaduto è stato riportato in modo piuttosto impreciso.
Descrive l'evento come epilogo di un avvicinamento a vista (no instrument approach available) e parla di ceiling (copertura delle nuvole) di 150/200 piedi. Sicuramente un avvicinamento a vista con quella base della copertura è praticamente impossibile. È più verosimile invece che si trattasse di "no precision instrument aporoach procedure available", ovvero un ILS/MLS/GLS di categoria I o superiore(cat I ha una decision height di 200 piedi AGL); ergo si trattasse di un avvicinamento tipo VOR, GNSS o RNAV, NDB che potrebbe aver lasciato l'aereo a 250 piedi di MDH (minimum decision height), con le difficoltà connesse col tipo di avvicinamento non precision e i relativi riferimenti visivi per completare l'atterraggio.

I meant exactly that, there is no instrument procedure available (legally and officially at least), no instrument approaches have been published, no ILS, no VOR (no such systems on the aerodrome), no NDB (NDB is available on the aerodrome), no RNAV (GPS, ...), thus no instrument approach procedures can legally be used. The aerodrome is strictly visual approach only.
What may have been done however is the use of GPS for positioning the aircraft (not legal), or even the NDB on the aerodrome (also not legal for approach and landing).

Thank you for your answer. This "self positioning" is something you suppose or is common practice at this aerodrome?
Re: Wamen: hard landing e gear collapse per un 737 di Trigana
I concur. Thanks Simon!

Dopo aver avuto ospite sul forum 'nientepopódimenoche' Mr AVHerald in persona, vorrei farvi notare che:
Ora, capisco l'autorevole fonte da cui provenga la notizia in se e l'approfondimento da me sollecitato su quale procedura avrebbero eseguito i piloti, ma qui vi è pure un rapporto preliminare bello e confezionato da dare agli inquirenti per partire coi findings e archiviare il caso!

Hello, OneShot,
It is a (technical) possibility even though (legally) not permitted. I am not saying it was done here nor am I saying to was NOT done, nor am I saying that it is common practise or it is NOT common practise, I have no specific knowledge or evidence.
The video evidence is certainly interesting showing the aircraft pop out of cloud very late (watch the video we published in the first seconds, and watch ABOVE the aircraft holding short on the taxiway), you'll be able to see where the Trigana Boeing popped out of cloud (video was taken by a well known pilot MD!) - she then disappears behind the holding aircraft, hits the runway hidden by the waiting aircraft and then is seen again on its "skid by".
Servus, Simon
