A Navy investigation is inserting blame on a mistake by a pilot for inflicting the crash of an F-35C Lightning II fighter jet aboard the plane service USS Carl Vinson within the South China Sea final yr.
The Jan. 24, 2022, crash, which spurred consideration with leaks of dramatic video of the accident in addition to hypothesis over the plane’s restoration, was the results of the pilot selecting to carry out a specialised touchdown however failing to change on digital aides within the aircraft designed to assist, the investigators concluded.
The crash injured the pilot, in addition to 5 sailors on the service’s flight deck. It additionally prompted hundreds of thousands of {dollars} in injury to a different aircraft and tons of of hundreds of {dollars} in injury to the deck of the service, the report mentioned.

The report, which was supplied to Navy.com by the Navy, mentioned that the pilot, recognized solely by his rank of lieutenant, wished to strive an “expedited restoration maneuver” that naval aviators know because the “Sierra Resort Break” or SHB.
The report describes it as “when an plane initiates a flip to downwind from both behind the ship or excessive of the ship … [using] G-forces to decelerate over the course of a 360-degree flip, dropping the touchdown gear when the plane is beneath touchdown gear transition velocity.”
Nonetheless, former Navy fighter pilots have a tendency to explain the transfer — which has a flamboyant repute — as “an actual loud present of drive,” as Cmdr. Man Snodgrass instructed Enterprise Insider in 2020.
In line with Snodgrass, in an SHB, “you go screaming over the plane service, after which, proper as you attain the tip of it, that is if you peel away and are available round to land.”
The report notes that the transfer means “a pilot has a lowered period of time to configure the plane and conduct touchdown checks.”
The pilot on this incident “wished to strive a ‘benign first try’ at breaking overhead the ship” and instructed others in his squadron that, since different junior officers had carried out the maneuver, “he wished to aim it earlier than the tip of deployment.”
Because the practically four-hour flight got here to an finish, the pilot started maneuvers to execute the break. Nonetheless, the report notes that he did not get an opportunity to complete the touchdown guidelines, the report mentioned. Crucially, the lieutenant reportedly did not activate the Strategy Energy Compensation Mode (APC), which maintains the jet on the proper angle, or the Delta Flight Path (DFP), which robotically adjusts the throttle.
Consequently, the investigation discovered that, whereas the pilot was making the proper corrections within the cockpit, “these corrections didn’t interact the engine to supply further thrust.”
Simply shy of 90 seconds after the aircraft started its break maneuver, the touchdown alerts officer aboard the service instructed the pilot his velocity was too low. A second later, they have been waiving the pilot off the touchdown and repeatedly telling him to hit the afterburners.
This second was captured in video clips shot by the ship’s flight deck cameras, which have been subsequently leaked on-line. Audio from the clips captured the second the “waveoff” and repeated “burner” calls went out.
The aircraft struck the rear of the Carl Vinson 4 seconds after these orders went out.
In line with the report, the aircraft hit the service’s ramp with its stomach, shearing off the principle touchdown gear. Then, a missile bracket on the aircraft’s wing caught one of many touchdown wires on the service’s deck, sending the jet right into a spin.
Investigators mentioned that this was a lucky flip of occasions for these on the flight deck for the reason that snag and spin “doubtless saved the [aircraft] fuselage wreckage from impacting different personnel, floor tools and plane parked on the 4 row [sic] of CVN 70’s bow.”
The pilot ejected earlier than the aircraft careened off the aspect of the ship and into the South China Sea. The whole incident took about 5 minutes. 4 minutes later, the pilot landed within the water, the place he was recovered by a rescue helicopter.
The report notes that on deck, crews sprang into motion, dousing bits of the wreckage with firefighting foam and responding to accidents. A minimum of one of many injured sailors was on the platform the place the touchdown alerts officers sit.
In the end, along with the pilot, a lieutenant commander, a chief petty officer, a petty officer top quality and two airmen have been injured within the mishap. Three sailors needed to be evacuated ashore; none is known as within the report.
The injury the aircraft prompted was vital. A close-by EA-18G Growler was showered with particles that broken its radome, a number of management surfaces and fuselage. The report concluded that the restore price would “doubtless cross the $2.5 million threshold of a category A aviation mishap.”
The crash additionally meant flight crews needed to exchange all of the arresting wires on the flight deck straight away, and the ship was left with a number of gouges and scrapes. Investigators mentioned the repairs to the flight deck alone would doubtless price round $120,000, and the sum of all of the injury to the service was in all probability no more than $600,000.
The aircraft, which sank into the ocean, was ultimately salvaged by the Navy in March 2022.
The report mentioned that the aircraft — which price $115,395,938 — was a loss. “A number of weeks of saltwater intrusion at depth will doubtless outcome within the lack of salvage potential for any plane parts,” the report mentioned.
Earlier than the incident, the pilot — a junior officer who had logged 650 flight hours, 370 of them within the F-35C — was judged as “distinctive for a first-tour junior officer,” the report mentioned. It famous that the lieutenant gained the “Prime-5 Nugget and a Prime-10 ball-flyer” awards inside his air wing.
“It’s the opinion of this board that pilot error was the reason for the mishap,” the report famous. “Nonetheless, the error was not performed in a reckless method nor with malicious intent.”
Navy spokesman Cmdr. Zach Harrell instructed Navy.com in an e mail that, for the reason that incident, “the pilot is now not in a flying standing within the U.S. Navy, however will proceed to function a Naval officer.”
Investigators additionally issued a sequence of suggestions to stop additional incidents. These included the change to all the time use Strategy Energy Compensation Mode (APC)/Delta Flight Path (DFP) throttle assists and that head-up shows contained in the cockpit embody indicator lights exhibiting when the 2 flight aids are on.
Nonetheless, the report particularly says that the Navy is just not recommending an finish to expedited restoration maneuvers or SHBs.
“Though the expedited restoration was a think about time compression,” the report notes, “this mishap occurred as a result of the [pilot] failed to pick out APC/DFP at any level in the course of the 27 seconds between the reducing of the touchdown gear and subsequent affect with the flight deck.”
