Note 1: FAA AD 2008-05-09 refers. Note 2: This Airworthiness Directive is applicable to the front row seats only. Modification to seats 3 & 4 (2nd row) is not mandated by this Airworthiness Directive. Compliance: Within the next 50 hours time-in-service after or within the next 6 months, after the effective date of this Airworthiness Directive, whichever occurs first. This Airworthiness Directive becomes effective on 8 May 2008. Background: This AD results from reports of the seat base/back attach bracket failing where it is welded to the seat base. We are issuing this Airworthiness Directive to prevent failure of the seat base/back attach brackets, which could result in the seats collapsing backwards during flight with consequent loss of control.
