More than 100 operators of Boeing’s 737 Next Generation (NG) will need to inspect the aircraft after ‘cracking issues’ were discovered on some of the manufacturer’s planes.
The Federal Aviation Administration (FAA) ordered the inspections after Boeing warned the US regulator that issues had been uncovered during modifications on heavily used aircraft.
Cracks were found in the pickle-fork area of some planes, where the wings meet the body of the aircraft.
The FAA said it is instructing all operators of the aircraft to conduct specific inspections and make any repairs in addition to reporting their findings.
In total, 117 airlines use the 737 NG, including the likes of Spice Jet and EgyptAir.
It is unclear how many of Boeing’s aircraft will be inspected but the company confirmed to the BBC that it will work with airlines to “implement a recommended inspection plan”.
In a statement, the FAA said that that subsequent inspections uncovered “similar cracks in a small number of additional planes.”
The ‘cracking issues’ do not affect 737 Max or P-8 Poseidon planes, according to reports.
The 737 Max has been grounded since March, as investigators evaluate its safety following fatal crashes in Indonesia and Ethiopia, which claimed 346 lives.
