Osprey crash was caused by pilot's decision to keep flying with cracks in a gear​




On the day of the crash, the Osprey was flying along the coast of mainland Japan headed to Okinawa when the first indications of trouble began.


In aircraft, vibrations are monitored as signs of potential trouble. A data recorder noted vibrations on the left side of the driveshaft that links the two engines and acts as a fail safe in case one engine loses power.


A second vibration followed. This time one of the five pinion gears inside the left proprotor gearbox was vibrating.

Hoernemann was likely balancing split priorities in his decision-making, the investigation found. He was leading the airborne portion of the military exercise and had spent months planning for it.


Until almost the final minutes of flight, he kept his primary focus on completing the exercise, not the evolving aircraft situation, the investigation found. He rejected his co-pilot's suggestions on using an alternative onboard mapping tool to identify the closest airfield to land. Throughout the flight, the co-pilot was also not direct about "his uneasiness with the evolving issues," the investigation found, based on the recovered voice data.


The fourth and fifth chip burn warnings came fast. Then with the sixth, escalation: just chips. It meant the Osprey could not burn them off. "Land as soon as practical" turned into "land as soon as possible." Still, the crew members did not act with urgency.


The final minutes of doomed flight​


In the final minutes of flight, they had begun to position the aircraft to land. The Osprey was half a mile (0.8 kilometers) from an airfield at Yakushima, flying about 785 feet (240 meters) above the water.


But they elected to hold for local air traffic to take off, even as Hoernemann confirmed over the radio they had an in-flight emergency.


The Osprey gave its final chip-related warning three minutes before the crash: chip detector fail. Hoernemann told the crew he was no longer worried, that he now assumed the earlier warnings were errors due to a faulty chip detector.


Investigators later found the fail message occurred because the detector "had so many chips on it, it couldn't keep up," Conley said.


Inside the proprotor gearbox, the pinion gear was breaking apart. At least one piece wedged into the teeth of the larger transmission gearing system, jamming and breaking off gearing teeth until the left proprotor gearbox could no longer turn the Osprey's left proprotor mast.

My brother is an aviation nerd and some of it rubbed on me. He's an engineer and I am bad at math, but I have an obsession with the SR-71 ever since I was a kid.
He also builds models, and when I was a few years old I stole an SR-71 he had assembled and used it as a toy for months until I left it in a bus. Sad.
Anyway, I recently learned that the only SR-71 outside of the USA is in England, at the Imperial War Museum in Duxford. This is much closer to me than the USA, so I guess a visit should be planned (as soon as things calm down).
 
Not cheap, but WOW.
There are worse ways to spend a couple grand.
 
Yeah, I noticed but SPITFRE.

Makes sense, the UK was one of the nations that hosted SR-71s during the cold war.
 
How could this get worse? But I bet they found money for Boeing to make another round of stock buybacks...
 
UK Government, RAF and Boeing yet to tell the truth. It was unsafe and they blamed the crew:

Chinook: Zulu Delta 576​

The Chinook helicopter disaster on June 2 1994 killed 29 people – 10 RUC, nine army, five MI5, one civil servant and four crew. What happened, its circumstances and effects have been much debated. And it remains a continuing source of heartache for the families of those who lost their lives.

The official conclusion was never accepted by the families of Flight Lieutenant Richard (Rick) Cook and John Tapper. Their search for the truth, and campaign to exonerate the names and reputations of their loved ones went on for 16 years.
