Arrester Hook

This teamwork, including the organization and facilitation of an Arresting Hook Summit by PMA-265 personnel, allowed the program office to dramatically reduce numbers of Issue Priority Group 1 (IPG1) aircraft and arresting hook back orders, said Mark Harris, the PMA-265 Landing Gear deputy assistant program manager for logistics (DAPML).

The arresting hook shortfall, which affected both F/A-18 Super Hornet and EA-18G Growler aircraft due to their shared airframe, was identified by NAVAIR nearly four years ago and was the result of the shutdown of the sole arresting hook repair facility, Harris said.

Bruce McIntosh, PMA-265 landing gear systems contractor support services, said NAVAIR Fleet Support Team (FST) provided notice about a processing error, identifying 151 subcomponents of the arresting hook assembly that needed to be replaced. The notification stipulated that aircraft found ashore with these subcomponents should not deploy, and aircraft that were already deployed were required to be inspected within 43 traps. After 43 traps, the tail hook components would be removed and turned in for maintenance. Affected hooks were moved to non-deploying aircraft in order to limit grounded aircraft.

McIntosh and PMA-265 Landing Gear DAPML Rick Lee discovered the demand for arresting gear hooks was much higher than the official 10 per month, something that was not immediately apparent. McIntosh and Lee notified NAVSUP, prompting them to start making spares purchases, searching for other sources to make repairs and begin the process of getting a contract for approximately 900 spare arresting hooks.

McIntosh and Lee set up an Arresting Hook Summit at Naval Air Station Oceana, Virginia, in 2018 to discuss ways to address arresting hook back orders and mitigate IPG1s, McIntosh said. They developed a plan with NAVAIR engineering for an extension on how many traps an arresting hook could perform in order to reduce the demand for spares and presented the plan to leadership at the summit.

The extension of traps combined with the qualification of two new tail hook repair sources and an aggressive delivery schedule for spares ultimately allowed PMA-265 to go from 73 IPG1s and over 150 back orders to zero IPG1s and roughly 20 back orders while simultaneously accommodating a monthly demand of 17 arresting hooks to support fleet operations, said Harris.

The LCA Navy fighter being used for arresting wire tests is based on the Tejas Mk. 1, and is powered by a General Electric F404 engine. It features a strengthened airframe, landing gear, and the tailhook.

Brief description of the issue:Currently on the F/A-18E the arresting hook/tailhook when lowered stops with the end a few feet above the ground. The hook should hang below the plane of landing gear ground contact points in flight and should drag on the ground when on deck. (The latter is necessary to engage short field/long field/overrun arresting gear if field arrested landing is directed for various emergency procedures.)

In June of 1990, Chris Grech from the Monterey Bay Aquarium Research Institute (MBARI) coordinated with the U.S. Navy's three-man deep submergence vehicle (DSV) Sea Cliff, to locate and document the Macon's remains. During the dives Sea Cliff recovered several artifacts from the site, and collected a definitive image of a Sparrowhawk arrester hook.

MBARI returned to the site in February and April of 1991 and videotaped the site using a remotely operated vehicle. The team located debris fields that included corroded girders, gasoline tanks, the nose-mounted mooring assembly, and the dirigible's German-made Maybach engines. The control car was also located. Although it was flattened, MBARI was able to record windows, chairs, chart tables, and a lead pencil. Four of the Curtis F9C-2 Sparrowhawk biplanes were also located revealing their aluminum frames along with some deteriorated wing fabric still intact. The 1990/91 surveys recorded the bow and mid-section debris fields. During these survey missions MBARI worked with the Navy to collect and distribute artifacts including the arrester hook from a Sparrowhawk. This artifact was conserved at East Carolina University.

The task is to catch the fighter and then bring it to a safe stop. This is achieved by installing energy absorbers, also known as brakes, such as the BAK-12 on both sides of the runway shoulders with a hook cable or a net barrier connecting the two energy absorbers.

Net barrier systems are installed in the overrun area of the runway. These arresting barriers such as the ATECH BAK-15 are installed as primary emergency recovery of fighter aircraft without a tail hook or as redundancy systems for hook-equipped aircraft.

Like all USAF fighters, the F-22 has an emergency hook, although in its case it is buried beneath a stealthy shroud that's incorporated into the jet's empennage. Daniel K. Inouye International has multiple runways equipped with the BAK-14 retractable arrestor gear system, which is essential equipment needed to support the co-located squadron of F-22 Raptors.

Most fighters have tailhooks, but they are not quite the same as the Navy type - they are for emergencies only. Basically, if the aircraft has problems landing, the base personnel lay out an emergency arrestor wire, usually tied to heavy chains - when the plane touches down, it snags the line, and slowly drags to a stop. It is not designed for the high sink rate landings carrier planes experience though.

the tornado hook is for emergency use only.when it was designed they gave the aircraft relatively small wheel brakes for the size and weight of aircraft, and the main force of braking on landing is provided by the thrust reversers. from memory the wheel brakes only provide approx 25% of braking required to stop.should a fault occur with the thrust reverse system the hook is dropped, and the RHAG (rotary hydraulic arrestor gear) wire is raised a little off the runway surface.

I have assigned all kinds of different button combinations on my joystick "X52 pro" but the tail hook will just not work. I know the default keyboard combination is LAlt + G key. I have tried that as well, and it just does not work.

The requirement is that the gear must be down before the hook will deploy. That had me scratching my head for a while. Definitely worth checking that the game doesn't have multiple buttons or other controls assigned to the hook though.

I'm happy with most details as the MDF guide I have seems to be pretty comprehensive but I have one question regarding the tail/arrestor hook arrangement as this is proving to be a little elusive. I'd hoped to model the kit with the arrestor hook deployed but from all the pics/diagrams I've seen there is nothing showing it deployed when stationary, only in action photos when one is in the process of landing. I've looked at the sprue shots and instructions of the kits (I haven't bought it as yet) and the arrestor hook is not provided as a separate item and barely seems to be represented by just a small 'bump' at the base of the tail.

As Eduard kits are normally very highly detailed I would have expected the hook to available as a separate piece as it is quite important, however if it is never seen unless during the process of landing then I can see why and I can then build the kit accordingly but just want to check first.

IIRC, the arrestor hook on the Hellcat was deployed by the pilot pulling on a cockpit release lever. at which time it slid on rollers to the fully extended/down position. The hook assembly had to be manually returned and latched by one of the aircraft handlers after being disengaged from the arrestor cable. I believe it's up unless released by the pilot, and I'm sure the handlers got it back up pretty quickly so the point would not dig into the wood flight deck planking. @Tailspin Turtle probably can quote you chapter and verse on the subject.

ISTR that there is footage wartime footage of mechanics servicing the arrester hook on a Hellcat on Indomitable where it had been extracted from its housing. That was over on the Armoured Carriers website.

In a folding wing aircraft with a tricycle undercarriage in which the folding of the wings causes the centre of gravity of the aircraft to move behind the rear axle of the undercarriage, the aircraft tail is supported when the wings are folded by a strut 15, which is also an arrester hook for engaging wires on a landing deck for stopping the aircraft, retractable manually into a housing 10α near the tail of the aircraft. The arrester hook 15 is pivoted about an axis 16 to the aircraft and is extended and supported by a pneumatic jack 20 whose piston 19 is pivoted at 18 to a lever 17 integral with the hook and whose cylinder is pivoted at 21 to a bracket 21α on the aircraft. The exhaust valve 36 of the jack 20 is automatically closed by a connexion 39, 38 to a lever 37 (see FIG. 4), fast on the shaft 16 when the arrester hook 15 is (manually) retracted, a lost motion device in the connexion preventing the automatic opening of the valve 36 by extension of the strut.

Made from the deck hooks of aircraft, the book ends were likely presented as a gift to Dyer when he left his position as commander of Canada's Atlantic fleet for a posting in Ottawa. Dyer had earlier served in the Canadian aircraft carriers HMCS Warrior and HMCS Magnificent. These hooks, attached to an arm beneath an airplane's tail that could be raised and lowered, were designed to catch arrester cables that slowed and stopped aircraft landing on carriers. 041b061a72
