Turkish Airlines has grounded its fleet of Avro RJ70s and RJ100s because of fuel tank contamination. The move surprised BAE Systems Regional Aircraft, who learned of it from press reports. THY operates three RJ70s and seven RJ100s, all of them leased from BAE Systems. They were initially delivered between 1993 and 1996, and have had their leases renewed several times, most recently in October 2002. One RJ100 was recently returned, and several others are scheduled to be returned in the near future. BAE Systems apparently did find some contamination in the RJ100 that was returned, but it only required minor repairs. BAE Systems is assisting Turkish to assess what action, if any, they need to take to return its remaining RJs to service.
