SRM - Definition

[JGreen]

Hi,

Can anyone shed any light on SRM definition - I know it stands for Structural Repair Manual, however I am looking at updating the allowable and repairable limits for the Fan Cowl doors for a large jet nacelle.

Currently the SRM only contains structural limits (stress/strain imposed), however the customer is asking for Fire, HIRF and lightning to be included.

I fully appreciate that the effects of these need be addressed, and included somewhere, but is the SRM the correct document ?

Thanks,

Julian

Hi!
I'm not sure I follow you completely... any repair stated in a SRM is supposed to maintain the a/c status it had when certified. If your engineers are doing their job this should be taken care when they make up the repairs? Or am I completely off the track here?

With "large fan cowl doors" I sense some confusion. Most large jets don't have cowl doors in the fan section, but maybe right behind it, and some are quite complicated, also acting as reversers. In many cases repairs to these locations are very limited in the SRM and you must contact the manufacturer of the cowl doors for repair information or repair instructions. Are the other "demands" for fire and such you mention being given to you be the dreaded "contract maintenance rep?" Often these folks are not fully cognizant of the rules and regulations concerning structural repair requirements to assemblies and components.
