Pratt & Whitney on Monday has denied a report by the US Department of Defense's (DoD's) inspector general (IG) that has raised quality control violations of the F135 engine for the Lockheed Martin F-35 Fighter.
The Government Accountability Office (GAO) studied flight test data and concluded that the reliability of the F135 engines is “very poor (less than half of what it should be) and has limited” progress for the F-35 program, the DoD IG report stated.
Pratt & Whitney in reply to the reports stated that it disagrees with the conclusions drawn relative to engine reliability by the GAO. Our current F135 CTOL engine achieves and exceeds specification requirements (147% of required levels). The reliability of the F135 STOVL engine meets 119% of its current requirement.
“The report incorrectly assessed engine reliability, as it did not account for new designs that have been validated and are being incorporated into production and fleet engines. While the report lists some propulsion reliability concerns, the F-35 Joint Program Office and Services have validated our reliability performance and we will continue to enhance reliability for the fleet as it matures to minimize life cycle cost and support continued high rates of engine availability,” the company said in a statement.
Pratt stated the DoD’s Inspector General’s report “is based on their audit in November of 2014. Since then, P&W has worked aggressively to address the DoD IG's findings and corrective actions. This was an audit of P&W's quality system and F135 contractual adherence, not an audit of F135 product quality.
“None of these findings had any impact on the product performance,” the manufacture emphasized. “None of the findings has, or would have, affected the operational fleet, safety or mission capability of the aircraft or the F135 engine. As of mid-April, P&W has already implemented approximately 60% of our identified corrective actions, and all but one are scheduled to be completed by July,” the company stated.
Pratt & Whitney is ramping up the retrofits to operational F135 engines with a fix to the problem that led to a catastrophic engine fire last year in the F-35A Joint Strike Fighter. The company stated in its press release Monday that it is aiming to modify the entire fleet by the first quarter of 2016
Pratt and Whitney has won a $592 million contract for the seventh lot of F135 propulsion systems to power F-35 Lightning II aircraft for the US Defense Forces. In December 2013, a $263 million sustainment contract was previously awarded bringing the total LRIP 7 propulsion cost to $943 million
Pratt & Whitney has sued a titanium supplier for fraud, after questions over the material led Pratt to briefly suspend delivery of its engine for the F-35 Joint Strike Fighter Reuters reported Wednesday. Pratt said that A&P Alloys Inc, in West Bridgewater, Massachusetts, "intentionally submitted certifications falsely represent the pedigree and quality of its material," according to court documents filed in U
Within the last year, Pratt & Whitney has signed more than $10 billion in long-term agreements with more than 90 key product suppliers from across the globe, the company said in a statement. The agreements are helping to solidify the company's manufacturing network as it prepares for an increase in commercial and military engine production, the statement added
