The US Federal Aviation Administration (FAA) has issued an airworthiness directive (AD) calling on operators of Boeing 737NGs and Max jets to inspect the emergency oxygen generators to prevent a potential failure of the system during a depressurization. The AD calls for operators to "ensure passenger service unit (PSU) oxygen generators are in the proper position on certain Boeing 737-8, -9, -8200, -700, -800, and –900ER series airplanes". It was "prompted by multiple reports of passenger service unit (PSU) oxygen generators shifting out of position within their associated PSU assemblies because of a retention failure". Boeing has investigated the condition and found that the oxygen generator retention failures were caused by a failure of the pressure-sensitive adhesive (PSA) material on certain generator strap thermal pads, the AD goes on to say. Cirium has contacted Boeing for comment. Operators affected by the AD will be required to undertake a visual inspection of the PSA to ensure that the thermal pad configuration and the retention straps are in the correct positions, and if not to take corrective action. "The oxygen generator is secured to the PSU assembly by two retention straps, with either PSA or non-PSA thermal pads. For all reported failures, the PSA thermal pad configurations were under the retention straps," the AD states. "This condition, if not addressed, could result in shifted PSU oxygen generators that might become non-functional, which could result in an inability to provide supplemental oxygen to passengers during a depressurisation event." The AD affects 2,612 US-registered aircraft and requires the inspections and rectification to take place within 120 to 150 days, depending on aircraft configuration.

Garuda Indonesia and Singapore Airlines have received approval from the Competition and Consumer Commission of Singapore (CCCS) for their commercial joint-venture agreement. The carriers say in a joint press release that the approval allows them to deepen their commercial partnership, including by operating joint revenue-sharing flights between Indonesia and Singapore, co-ordinating flight schedules, and exploring joint sales and marketing initiatives. Garuda and SIA signed the agreement in May 2023. The airlines codeshare on several flights, including from Bali, Jakarta, Medan, and Surabaya in Indonesia, and on long-haul routes from Singapore to Johannesburg, London Heathrow and Mumbai. "With the CCCS's approval, we are poised to deepen our collaboration across a wider scope of commercial activities," states SIA chief Goh Choon Phong. "Along with the ongoing work to strengthen the links between our frequent-flyer membership programmes, this will provide our customers with even more options and enhanced value."

SR Technics has expanded its Pratt & Whitney PW4000 engine maintenance agreement with South Korea's Asiana Airlines for the next five years. The MRO provider says it has been maintaining Asiana's fleet of 15 Airbus A330s for the last five years and will now extend this relationship through June 2029.
