Kinda like Sikorsky's reported dry transmission run times. 
Cougar flight 91 accident. 

Prior to the initial certification tests, Sikorsky advertising material indicated that the S-92A had a 30-minute run dry capability. This advertising information was picked up by prospective operators, various trade journals, and internet sources. After failing to demonstrate that the MGB was capable of successfully completing the loss of lubricant test, Sikorsky changed its material to indicate that the S-92A had a "thirty minute safe operation following an oil leak" capability. The wording of this statement was close enough to the original wording, which specifically mentioned a run dry capability, to potentially lead some to believe that the S-92A had a 30-minute run dry capability. In addition, instances such as the 2007 marketing comparison of the EC225 and the S-92A identifying that both helicopters have a 30-minute run dry capability indicates that at least some Sikorsky marketing personnel were unaware that this capability had not been achieved during certification or that some older marketing material had not been updated following the loss of lubricant test. Even with limited distribution, this type of marketing information would serve to reinforce any perception that the S-92A had a 30-minute run dry MGB.
