WestJet Selects Jetaire’s INVICTA ™ for Fuel Tank Flammability Compliance for Boeing 737

Agreement between WestJet and Jetaire Flight Systems initializes previously announced partnership with KF Aerospace to provide services on Canadian operated aircraft

Jetaire Flight Systems, manufacturer of the only patented reticulated polyurethane foam (RPF) solution designed for Boeing 737 aircraft has been chosen by WestJet to bring their fleet into compliance with the Fuel Tank Flammability Reduction Rule (FTFR). The selection of INVICTA ™ by the leading Canadian low-cost operator reiterates WestJet’s commitment to safety and compliance well ahead of the mandatory scheduled date for adherence.

WestJet operates more than 200 routes to over 100 destinations in 25 countries. The Calgary based airline has expanded through acquisitions including the addition of Swoop and recently announced, Sunwing which will both be integrated into the WestJet fleet.

An integral function of fleet management, airworthiness directive compliance is critical for ensuring the safety of passengers, crew, and aircraft. Airlines consistently seek efficient and fault-free solutions to meet mandatory compliance requirements, and INVICTA ™ provides the only solution to meet both demands related to flammability reduction.

INVICTA ™ by Jetaire Group utilizes a proprietary Reticulated Polyurethane Foam (RPF) that reduces the incidence of explosions. The foam is a lightweight, self-extinguishing, three-dimensional skeletal matrix that suppresses fuel ignition caused by heated fuel vapor, tank rupture, lightning strike, static discharge, or outside factors.

Michael Williams, Jetaire CEO, explained “The adoption of INVICTA ™ by WestJet is a significant order that represents the commercial aviation industry’s acknowledgement of our innovative, patented technology. We are pleased to support WestJet engineering and flight operations through our partnership with KF Aerospace,” Williams added.

Jetaire Group recently received Transport Canada (TCCA) approval for the firm’s supplemental type certificate (STC) on its B737NG INVICTA ™ modification to bring aircraft into compliance with airworthiness directive AD 2020-18-13. Installation of the INVICTA ™ modifications will take place under a recently announced agreement between Jetaire Flight Systems and Kelowna, British Columbia based maintenance, repair, and overhaul (MRO) facility, KF Aerospace.

On the working agreement with KF Aerospace, Williams stated that “Canadian airlines are familiar with KF Aero and with operations across the country, they provide easy access for aircraft to be modified for compliance quickly and with minimal downtime.”

KF Aerospace is Canada’s largest commercial maintenance, repair, and overhaul group, operating facilities in Kelowna (YLW), Hamilton (YHM), Portage La Prairie (YPG), and Vancouver (YVR). Widely known for providing heavy maintenance, modification services, and line maintenance, KF Aerospace holds approval for maintenance performance on several Boeing and Airbus aircraft types that match the supplemental type certificates held by Jetaire Group.
