Required Safety Modifications - Who Pays?

Tue Apr 03, 2012 9:49 pm

Was just reading through the Wikipedia article on flight BA 38 that crashed short of the runway due to ice accumulating in the heat exchangers in the engines. In situations where modifications are a critical safety concern due to a design flaw, who is responsible for the cost of the replacement parts? Would Rolls Royce be responsible for the costs of sending out replacement parts to all operators or would Boeing and the airline share (aside from the man hours to actually replace it) part of the costs as well? Would it be like a faulty car component being recalled and replaced at no cost to you or is it more complicated than that?

Airplanes that are in the warranty period of time will have the parts sent free to the airline and compensation for the labor associated with the modifications. Airplanes outside of warranty are responsible for paying for it on their own.

The question I am not answering is what constitutes if an airplane is in warranty. It depends on the airplane, operator and type of repair. For economic improvements, warranty usually does not cover them except within a certain window. For defective designs covering safety, it typically does. Warranty almost never applies after the airplane has been transferred from its first airline to a second airline (unless it is owned by a leasing company and they have different rules).
If you have never designed an airplane part before, let the real designers do the work!

If the failure is Design/Production related...The Manufacturer normally ensures that the mod & the costs are catered to.
I may not win often, but I damn well never lose!!! ;)
