An accident on the Vikramaditya.

MiG 29K averts horror crash, but slams onto India's 'brand new' naval icon, INS Vikramaditya

On failed landing, MiG 29K looks to take-off, but caught in last 'arrester wire', causing it to slam into INS Vikramaditya .

A MiG 29K naval combat aircraft has suffered damage while landing on the aircraft carrier INS Vikramaditya during operations in Arabian Sea off the coast of Goa, a Navy official said today.

The Russian-origin aircraft had taken off from the Naval airbase INS Hansa in Goa yesterday and was landing on the aircraft when it carried out a 'hard-landing' causing damage to the nose-wheel undercarriage, the official said.

The pilot of the aircraft is safe and the further details of the damage are being assessed, they said.

The Navy has ordered a Board of Inquiry (BoI) into the incident on the aircraft carrier procured from Russia at a cost of over Rs 15,000 crore late last year.

In this incident onboard the 44,500 tonne warship, the pilot missed the first two arrester wires used as aid by the pilot for landing on the carrier and while he was trying to take off again, it got stuck in the third arrester wire causing a hard-landing, Navy officials said.

MiG 29Ks have been procured by India from Russia and India is the only country in the world which operates these twin engine naval fighters.

India has ordered for 45 of these aircraft and this is the first accident involving these aircraft.

Just a small touch of bad news for the Aussies also..:(

Damage to the ship was minimal.

A CIVILIAN contract crew made two serious errors during sea trials for the navy’s biggest ever ship, damaging its hull and melting down electrical systems.

The first of two $1.5 billion 27,000-tonne Landing Helicopter Docks (LHDs), to be known as HMAS Canberra, suffered excessive vibration in May during her first “shakedown cruise” between Melbourne and Sydney.

The fault was traced to the brand-new vessel’s two German-built Siemens propulsion pods — or azimuth thrusters — which were out of alignment.

Each thruster, fitted at the stern of the ship, has two propellers mounted on large electric powered pods that can be rotated to any angle, eliminating the need for a rudder. And just like the wheels of a car, poor pod alignment causes vibration.
A crew from Teekay Shipping Corporation was hired by prime contractor BAE Systems and was apparently unaware that the pods must be operated in tandem above eight knots.

They ran them independently in low-speed mode at high speed, causing serious vibration throughout the ship.

“Once the pods were back in the correct mode the vibration ceased,” a project source said.

“It was an operator error and the return journey was much smoother.”

The vibration was generated by cavitation and the bounce produced at the stern rolled across the ship with decks trembling and panels vibrating.

“It was like the shaking floor in an amusement park house of fun,” a source said.

Damage was minimal, but vibration caused paint to be stripped from the ship’s hull directly above the pods.

The crew’s woes continued when Canberra returned to Port Phillip Bay and was forced to drop anchor for four hours after losing steerage following an electrical power failure.

Unfortunately the operators forgot to disconnect the emergency power and when the main power kicked back in the circuit breakers melted.

“There were no major design errors during the trials and both issues were operator errors,” the source said.

“The trial didn’t go as well as hoped, but it was better than expected.”

In addition to the serious errors, excessive corrosion was detected in propeller nuts and a small crack was discovered in the hull of the ship that was caused during its long journey on a barge from the builder in Spain.

The Canberra will be back at sea in July for the next round of trials before she is handed to the Navy later this year.

News of the botched sea trials comes as the government announced it would insert an “experienced shipbuilding management team” into taxpayer-owned shipbuilder ASC in Adelaide to fix the troubled $8.5 billion Air Warfare Destroyer program.

Defence Minister David Johnston and Finance Minister Mathias Cormann said the team would target productivity and production schedules in a bid to get the controversial three-ship alliance project back on track.

Wow. Operator error of this nature...not knowing that the pods had to be run in tandem at high speed, and then forgetting to stop the backup power when going back to normal power have to be pretty embarassing.

Thank goodness no major damage occurred.

Why not hire some crew who had helped with the Spanish ship of exactly the same design? I bet BAE could have found them.

Popeye, if you do not mind, I will post this to the Australian Military News thread as well.

I found this story at mp.net and this is what I posted;

That's why they do sea trials, folks.

Exactly.. when you read the entire article this statement stands out

Damage was minimal, but vibration caused paint to be $tripped from the ship’s hull directly above the pods.

The crew’s woes continued when Canberra returned to Port Phillip Bay and was forced to drop anchor for four hours after losing steerage following an electrical power failure.

The Canberra will be back at sea in July for the next round of trials before she is handed to the Navy later this year.

In case anyone wants to know USS George H W Bush (CVN 77) returned to the ship yard for six months a mere six months after being commissioned and was in the shipyard for six months.

The press is trumping this up in India like it is somekind of horrible, narrowly averted complete disaster.

Sorry...but it is really, absolutely no huge deal.

The aircraft trapped the third wire and hit a little hard, damaging the front nose wheel.

Minor damage to the aircraft. No damage to the carrier. No personnel injured.

Landing high performance jets using arrestor wires on an aircraft carrier that is moving and being impacted by the seas is an inheritantly dangerous thing. These pilots are just getting certified, or have just been certified on the Virkamaditya. They have some good experience at their land based facility and many of them with the Goshawk on US carriers. But they are now having to learn to do it...and do it often...on their own carrier.

Accidents like this happen fairly often on US carriers and they just keep on going. Sadly, there are pilots who are injured or killed as well. That's part of the price, sadly, that is paid to have this type of capability and every one of those pilots knows this when they sign up for it.

Jeff, 100% truth spoken.^^^ Hard landings occur more often that one would imagine.

Once aboard Nimitz a Tomcat made a hard landing and sheared off the STBD landing gear. The aircraft was quickly moved out of harms way. FOD walkdown occurred to clear any debris and recovery of aircraft started again in about 15 minutes time. Fact.

There was major damage to the Tomcat.Shearing off a landing gear is major..no damage to the ship or anyone aboard.

On CVN-79 Expectations:

Posted on InsideDefense.com: June 10, 2014

The Navy is bracing for a six-month delay in the delivery of its next aircraft carrier, the John F. Kennedy (CVN-79), estimating in a report to Congress that shipbuilder Huntington Ingalls Industries will complete the second Ford-class ship in March 2023.

The slip from the previous September 2022 estimate, which is attributed to extended negotiations over a primary construction contract, would consume all of the margin in the Navy's approved acquisition baseline for the delivery of the Kennedy.

The Navy postponed the main contract award for the Kennedy last fall, following a wide-ranging Government Accountability Office audit of the CVN-78 program that identified significant cost increases and recommended the service defer the CVN-79 detail design and construction contract until land-based testing for critical ship systems is complete.

In an April 16, 47-page Selected Acquisition Report on the three-ship CVN-78 program, the Navy formally explained the impact of that contract award delay on two near-term milestones for the Kennedy: a planned October 2013 Defense Acquisition Board review will now take place this October; and the start of construction, previously scheduled for September 2013, is now slated for December.

"In order to afford an opportunity for [the] Navy and the shipbuilder to incorporate further construction process improvements and Government Furnished Equipment cost reductions into the construction plan while continuing negotiations for the Detail Design and Construction (DD&C) contract award, the CVN 78 Class Aircraft Carrier Program has changed its estimates for the CVN 79 Defense Acquisition Board (DAB) Program Review (PR) and DD&C contract award dates," the report states.

In January 2009, the Navy awarded HII's Newport News Shipbuilding a contract -- now estimated to be worth $2 billion though fiscal year 2013 -- for CVN-79 construction preparation, to execute "advanced construction, material procurement, as well as research, design and engineering efforts."

In October 2012, the Navy solicited a fixed-price-incentive contract bid from HII for CVN-79 detailed design and construction, with a goal of awarding the contract, and commencing construction, last summer. Following the GAO report -- as well as concerns from lawmakers about cost growth in the aircraft carrier program -- the Navy postponed plans to award the Kennedy construction contract.

The Navy last year established an $11.4 billion cost cap for the second Ford-class aircraft carrier. The CVN-78 program -- successor to the Nimitz-class carrier -- is a three-ship acquisition effort that the Navy estimates will cost $43.3 billion to procure through 2028.

Navy officials say they are striving to incorporate lessons learned from first-of-class difficulties with the aircraft carrier Gerald R. Ford to reduce costs in building the Kennedy.

Exactly, when you roll onto the deck the thrust levers are advanced, just in case you do not trap, in this case the Indian pilot likely rotated a little prematurely, assuming he had missed the wires, as the nose comes up the tail goes down, placing the hook in firm contact with the deck. As we have reminded all along, bringing an aircraft aboard ship is dangerous, and it requires one to place some of your normal reflexes on "manual override".....this is SOP, and it will happen again....you debrief, and allow the process to happen, hopefully the pilot will be trapping at the land based facility today, and out to the carrier again! and yes, it IS rocket science, even with all the advanced landing aids, and it is hairy, every time! Go Vik! and Go Mig 29K.....

In this incident onboard the 44,500 tonne warship, the pilot missed the first two arrester wires used as aid by the pilot for landing on the carrier and while he was trying to take off again, it got stuck in the third arrester wire causing a hard-landing, Navy officials said.

There are a lot of innacuracies in that sentence above from the article. It implies the pilot uses just the wires as a guide which is obviously wrong. The LSO and the Christmas tree play an even larger role.

Also how many wires are there on the Vik? 3 or 4? pilots usually aim for the 3rd. No naval aviator would try and aim for the first because that's asking for trouble. It means you're landing to close to the stem and could potentially crash into the carrier.
It carrier quals a pilot who consistently misses the 3rd wire is also deemed not very competent and may also effect promotion.
