Airworthiness Directive · Amendment 39-22287 · Navigation
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., Model BD-700-2A12 airplanes, certificated in any category, serial numbers 70006 through 70084 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-2A12 airplanes. This AD was prompted by a report of a lateral offset observed on the head-up display (HUD) of several airplanes between the synthetic vision system (SVS) and actual runway due to mechanical misalignment of the HUD during manufacturing and assembly. This AD requires revising the existing airplane flight manual (AFM) to prohibit steep approach landing (SAL) and enhanced flight vision system (EFVS) operations. This AD also requires calibrating the HUD. The FAA is issuing this AD to address the unsafe condition on these products.
Within 30 days after the effective date of this AD, revise the existing AFM to include the information in the sections of the AFM specified in paragraphs (g)(1) through (3) of this AD.
(1) Section 6., Service Bulletins, Chapter 1—Introduction, Bombardier Global 7500 AFM, Publication No. CSP 700-7000-1, Revision 18, dated August 18, 2022.
Note 1 to paragraph (g)(1): For obtaining the sections and supplements of the Bombardier Global 7500 AFM, Publication No. CSP 700-7000-1, specified in paragraphs (g)(1) through (3) of this AD, use Document Identification No. GL 7500 AFM.
(2) Supplement 7—Enhanced Flight Vision System (EFVS) Operations, Chapter 7—Supplements, Bombardier Global 7500 AFM, Publication No. CSP 700-7000-1, Revision 18, dated August 18, 2022.
(3) Supplement 20—Steep Approaches with Published Glidepath Angles from 4.5 to 5.5 Degrees, Chapter 7—Supplements, Bombardier Global 7500 AFM, Publication No. CSP 700-7000-1, Revision 18, dated August 18, 2022.
Within 27 months after the effective date of this AD, calibrate the HUD and second HUD (if installed), including a general visual inspection of the HUD mounting brackets and sill beams for damage and contamination (e.g., drill shavings and adhesive) of the mating surfaces and injection holes, a general visual inspection for voids in the structural adhesive, and applicable corrective actions, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 700-34-7521, Revision 03, dated July 27, 2021, or Bombardier Service Bulletin 700-34-7521, Revision 04, dated December 6, 2021; and Bombardier Service Bulletin 700-34-7523, Revision 01, dated December 8, 2021; as applicable. All corrective actions must be done before further flight.
