US Air Force clears Ospreys to fly amid unresolved clutch problem
WASHINGTON — The Air Force cleared its
CV-22 Ospreys tiltrotor aircraft to resume flying, some two-and-a-half weeks after grounding them due to a clutch problem that remains unresolved.
Lt. Gen. Jim Slife, head of Air Force Special Operations Command, on Friday authorized the command’s fleet of 52 Ospreys to resume flying, with measures to limit the risk from “hard clutch engagement” incidents. AFSOC Spokeswoman Lt. Col. Rebecca Heyse said the aircraft are expected to start operating again this weekend…..
Heyse said AFSOC is still not sure why the Osprey clutches are slipping, but that the command has put steps in place to try to manage them for the near term. AFSOC studied the data from all 15 recorded hard clutch engagement incidents across the Osprey enterprise to figure out what was a common factor there.
One key risk mitigation step: AFSOC has instructed its Osprey pilots to take a two-second pause immediately after taking off to keep the clutch from slipping, instead of going to full power immediately, Heyse said.
Marine Corps officials told reporters last month that its Osprey pilots are instructed to hover after taking off to check instruments and ensure the clutch isn’t slipping.….
“Until a root cause is identified, and solution implemented, the focus is on mitigating operations in flight regimes where [hard clutch engagements] are more prevalent and ensuring our aircrews are trained as best as possible to handle [them] when they do occur,” Heyse said in an email.….
