Key Points:
- Boeing has asked operators of Boeing 737 MAX aircraft, including Air India Express, SpiceJet, and Akasa, to inspect tie rods controlling rudder movement for loose hardware.
- The B737 MAX was previously grounded globally but was allowed to fly again after safety improvements.
- This issue does not impact the operations of Akasa and SpiceJet.
Boeing has requested that operators of its Boeing 737 MAX aircraft, such as Air India Express, SpiceJet, and Akasa, conduct safety checks on the aircraft due to a loose bolt found in one of the planes. The inspection involves checking specific tie rods that control rudder movement for loose hardware. The Directorate General of India (DGCA) confirms that the necessary checks are being carried out in compliance with Boeing’s instructions. Akasa, which operates 20 B737 MAX aircraft, states that its operations will not be affected by this issue, and it will follow the recommended checks and procedures. SpiceJet, with 12 MAX aircraft in its fleet, also states that the issue will not impact its operations. AI Express, which operates nine MAX, is reportedly taking the required steps as well. These Indian carriers have a combined fleet size of over 40 B737 MAX aircraft.
Rudder control is essential for an aircraft’s lateral movement and helps it turn left or right. The inspections were recommended by Boeing after an international operator discovered a missing nut while performing routine maintenance on the rudder-control linkage. The B737 MAX was previously grounded globally from March 2019 to December 2020 following two fatal crashes. After implementing safety improvements, the aircraft was certified safe to fly again. Indian carriers have placed hundreds of orders for the B737 MAX.
This new issue arises at a time when Pratt & Whitney’s engines for Airbus A320neo, which are prone to snags, are also causing concerns. IndiGo currently has 50 grounded planes due to the engine issue, and this number may rise to 80 in 2024 due to additional grounded planes requiring inspections for potential powder metal contamination. With the potential for more grounding of aircraft, fares may increase significantly, as was seen when GoAir collapsed last summer. The combination of ongoing issues with both the PW engines and the B737 MAX could contribute to further fare hikes.
