Direct-To Avionics Issues Recall On All Crossbow 425EX AHRS

Company Bites The Bullet And Supports Customers After Supplier Solutions= =20 Reportedly Fell Through 

3Dhttp://www.aero-news.net/#=20In a move that company officials ad= mit may=20 cost them as much as a quarter of a million dollars (for a product that they= do=20 not manufacture), Direct-To Avionics (D2A) has announced a full recall of th= e=20 Crossbow 425EX AHRS, a derivative of Crossbow's NAV420.

The recall affects over 100 aircraft.

Specifying unsuccessful long term efforts to reach a solution with suppli= er=20 Crossbow Technologies (and indeed, several months of paperwork confirms = ;the=20 extended nature of this problem), D2A will pay for the replacement of a= ll=20 the units in question... out of their own pocket.

Unresolved problems with the Crossbow 420 Series AHRS will also precl= ude=20 Direct-To Avionics from incorporating Crossbow in future experimental Chelto= n=20 Electronic Flight Instrumentation Systems (EFIS).
