A new supplemental type certificate gives owners of Textron Aviation’s earliest CitationJet aircraft a path to modernize their cockpits with an all-Garmin avionics suite. The approval expands upgrade options for operators seeking to bring legacy business jets’ avionics systems up to current standards.
July data from the U.S. Department of Transportation shows American Airlines’ mechanical disruptions have imposed a year-to-date cost equivalent to three Boeing 737 MAX 8s—more than twice United Airlines’ total, underscoring the operational and financial impact of maintenance-related reliability problems.
Safran Landing Systems has expanded its Singapore MRO center after a $22 million investment, increasing landing-gear overhaul capacity and adding nearly 100 jobs by 2030. Separately, ReGEN opened a components hub at Changi Airfreight Centre to improve used serviceable material access for Asia-Pacific airlines and MRO providers.
flydubai is launching a cabin retrofit program as its fleet exceeds 100 aircraft, adding lie-flat business-class seats and larger overhead bins. The changes represent an investment in onboard product and cabin capacity as the Middle Eastern carrier continues operating at scale.
Japan Airlines has extended its multi-year agreement with Embraer covering parts supply, maintenance and repair for 32 E170 and E190 aircraft operated by regional subsidiary J-AIR. The renewal supports faster access to critical components and sustained fleet availability across the carrier’s regional network.
The Air Force repaired a KC-135 damaged by shrapnel, highlighting the operational value of advanced maintenance performed closer to the front lines. Forward repair capacity can return damaged airframes to mission support sooner and help preserve available tanker capacity during sustained operations.
The FAA has proposed an airworthiness directive requiring operators to perform inspections on Pratt & Whitney PW1500G and PW1900G engines to address a high-pressure compressor issue. The mandated work would formalize inspections already outlined by Pratt & Whitney in service bulletins.
