"The UK should have options in the event of a diplomatic crisis with Turkey. I want to know what alternative arrangements are in place if it became impossible to have the engines overhauled," Kerevan, who is to call on the UK Defense Select Committee to investigate the issue, told BBC.
The F-35 jet, formerly known as the Joint Strike Fighter, is being built by US defense giant Lockheed Martin in partnership with other countries, including the United Kingdom, Australia, Canada, Denmark, Italy, Norway, the Netherlands and Turkey.
The United Kingdom was chosen by the F-35 Program Office to be a global repair hub for the aircraft, providing maintenance, repair, overhaul and upgrade services for the aircraft and components in November 2016.
On March 31, UK Defense Secretary Michael Fallon announced a $112-million contract for UK-based BAE Systems to support the upkeep of F-35 fighter jets.
A military coup attempt took place in Turkey in July 2016. It was suppressed by government forces, with over 240 people killed and an estimated 2,000 wounded. Ankara has accused dissident Muslim cleric Fethullah Gulen, who has lived in the US state of Pennsylvania since 1999, and his followers, of playing a key role in the coup.
