Lockheed Martin will retrofit the first 64 production models of the F-35A and F-35B, after discovering a second aluminium part supplied by US-based producer Alcoa failed in durability tests.
The redesigned wing forward root rib forgings will be installed on new aircraft ordered by the US Air Force and US Marine Corps in the fifth yearly lot of low-rate initial production, according to the F-35 joint programme office (JPO).
The new structural problem was revealed even as the test fleet was cleared to resume un-monitored flying on 26 August, after Lockheed fixed a problem with the F-35's power system.
On 2 August, the Honeywell integrated power package failed, after a valve malfunctioned during a routine ground test on the AF-4 test aircraft.
