Eirtech Aviation has won a major contract with WestJet, for the installation and maintenance of advanced warning cabin pressurisation systems for Canada’s second largest airline. The work scope will be carried out on WestJet’s Boeing 737 fleet. Ireland’s Eirtech Aviation was chosen for presenting a solution that was both time-saving and also cost-effective, enabling the fastest turn-around possible on installation and minimizing down-time for the fleet. It is an AMOC solution to a Federal Aviation Authority (FAA) Airworthiness Directive, which mandates a further level of warning and awareness for the crew by improving visual and aural annunciation in the cockpit, which will enable pilots to accurately and safely differentiate between take off configuration indicators and cabin altitude pressurization warnings. Eirtech Aviation’s design solution has already received all mandatory STC and AMOC approvals from the FAA, EASA and the Canadian Transport Authority.
