Models named: BD-100-1A10. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to all Bombardier, Inc., Model BD-100-1A10 airplanes, certificated in any category.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Within 24 months after the effective date of this AD: Inspect the SCU to determine if SCU part number (P/N) 46000-01 with a serial number listed in Figure 1 to paragraph (g) of this AD is installed on the airplane. A review of the airplane maintenance records is acceptable in lieu of the inspection if the SCU P/N and serial number can be conclusively determined from that review. If an SCU P/N 46000-01 with a serial number listed in Figure 1 to paragraph (g) of this AD is not installed on the airplane, or if the SCU identification plate is marked with SB100-32-030, then no further action is required by this AD; however, the installation prohibition in paragraph (i) of this AD still applies. Figure 1 to Paragraph (g)—Affected SCU Serial Numbers ER15FE24.018

Unsafe condition

This AD was prompted by a report of a steering control unit (SCU) filter plate connector that does not meet the certification requirements for exposure of electronic components to high intensity radiated field environments. The FAA is issuing this AD to prevent malfunction of the nose wheel steering (NWS) system. The unsafe condition, if not addressed, could result in un-commanded steering or lateral runway excursion.

Affected ADs

None.
