Airworthiness Directive · Amendment 39-18629 · Doors
Bombardier, Inc. Airplanes
This AD applies to Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes, certificated in any category, serial numbers 9002 and subsequent.
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by in-service reports of passenger door tensator spring failures, and qualification testing indicating that non-conforming tensator springs could be susceptible to failure prior to reaching their safe-life limit. This AD requires revising the maintenance or inspection program to incorporate certain temporary revisions, and replacing the passenger door tensator springs with new springs. We are issuing this AD to prevent tensator spring failure, resulting in the inability to open the main passenger door, which could impede evacuation in the event of an emergency.
Within 30 days after the effective date of this AD, revise the maintenance or inspection program, as applicable, to incorporate task number 52-11-41-101 as specified in the Temporary Revisions (TRs) identified in paragraphs (g)(1) through (g)(5) of this AD. The compliance time for doing the initial replacement of the passenger door tensator springs with new springs is at the times specified in the applicable TR specified in paragraphs (g)(1) through (g)(5) of this AD, or within 30 days after the effective date of this AD, whichever occurs later. The revision required by this paragraph may be done by inserting copies of the TRs identified in paragraphs (g)(1) through (g)(5) of this AD into the applicable Time Limits/Maintenance Checks manual. When the information in a TR has been included in general revisions of the applicable Time Limits/Maintenance Checks manual, the general revisions may be inserted in the Time Limits/Maintenance Checks manual, and the TR may be removed.
