Thanks Aldo. I'm not sure what you're getting at but this is interesting anyway. It may seem to some like the certificate is deliberately evasive regarding the model of the engine but that can't really be the case. It is just a bit vague that's all. If it says RB211 series then it is obvious that it's a 535. The 535 is the only member of the RB211 family that fits the 757... http://en.wikipedia.org/wiki/Rolls-Royce_RB211 The only thing we cannot confirm from the airworthiness certificate is the exact version of the 535 in question. Not that it would help much. You failed to point out another important piece of data from this document. The A/W date. This matches perfectly with the delivery date provided by planespotters.net (as we would expect). So all this tells us is that the 757 was certified airworthy on the day it was delivered to American Airlines (May 8th 1991) and at that time it had RB211 535s. |
