Canada’s WestJet has contracted Irish MRO provider Eirtech to carry out mandated changes to the cabin pressurisation systems on its Boeing 737 fleet.
The Shannon-based maintenance specialist has developed a solution to install additional cabin altitude indication and warning systems – which are required under a US Federal Aviation Administration airworthiness directive covering certain 737 models. The AD sets a deadline of May 2016.
Eirtech’s wiring installation avoids otherwise necessary testing of unrelated systems and thus reduces aircraft downtime, says the MRO provider’s chief executive Niall Cunningham.
The contract with WestJet covers installation and maintenance of the additional equipment.
