The parent company of defunct Indian carrier Kingfisher Airlines has filed a $234 million lawsuit against International Aero Engines (IAE) over the V2500 A5 powerplant.
The suit was filed by United Breweries in Bengaluru, and alleges that the engines "were inherently defective, both in design and manufacture". The revelation was made in the carrier's annual report for the 2012-13 financial year ended 31 March.
The suit seeks damages of $210 million in addition to Indian rupees (Rs) 1.6 billion ($24 million).
An airline spokesman contacted about the suit declined to provide further details. IAE officials were not immediately available for comment regarding the allegations in Kingfisher's annual report.
Kingfisher has been grounded since September 2012, and in its annual report, it states that it has defaulted on "payments to several creditors".
It attributed its problems to a "difficult operating environment as well as the engine problems".
Kingfisher was formerly a major operator of Airbus A320 family aircraft powered by IAE's V2500 engines.
Although the annual report offers few specifics about the suit, in August 2010, the carrier experienced problems with the V2500 that caused it to ground nine A320s.
On 17 August 2010, a company spokesman told Flightglobal Pro that the carrier had experienced "technical issues" with stage three to eight of the 10-stage high-pressure compressor in the engine, among other problems.
Subsequently, on 19 August 2010, IAE said it would replace parts on some of its V2500 engines on in-operation aircraft after discovering problems with the engine's high-pressure compressor drum in 2009.
