SUBJECT CATEGORY: Airworthiness Directives; Bombardier Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 Airplanes DATES: This AD becomes effective May 12, 2005.
The incorporation by reference of a certain publication listed in the AD is approved by the Director of the Federal Register as of May 12, 2005.
DOCUMENT SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC8102, 103, 106, 201, 202, 301, 311, and315 airplanes. This AD requires revising the airplane flight manual to include applicable procedures to follow when the flightcrew receives abnormal indications of airspeed, altitude, or vertical airspeed. This AD also requires modifying the static system. This AD is prompted by a report of a leak in the static pressure system, which could result in loss of the static systems and consequent erroneous data displayed on the pilot's flight instruments. We are issuing this AD to advise the flightcrew of applicable procedures in the event of abnormal indications of airspeed, altitude, or vertical airspeed; and to prevent leaks in the static system, which could result in the loss of critical flight information that could result in reduced controllability of the airplane or controlled flight into terrain.
The FAA proposed to amend 14 CFR part 39 with an AD for certain Bombardier Model DHC8102, 103, 106, 201, 202, 301, 311, and 315 airplanes. That action, published in the Federal Register on February 1, 2005 (70 FR 5078), proposed to require revising the airplane flight manual (AFM) to include applicable procedures to follow when the flightcrew receives abnormal indications of airspeed, altitude, or vertical airspeed. That action also proposed to require modifying the static system.
We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance The following table provides the estimated costs for U.S. operators to comply with this AD. [[Page 17595]]

20050717 Bombardier, Inc. (Formerly de Havilland, Inc.): Amendment 3914041. Docket No. FAA200520222; Directorate Identifier 2004NM 230AD. Effective Date (a) This AD becomes effective May 12, 2005. Affected ADs (b) None. Applicability
(c) This AD applies to Bombardier Model DHC8102, 103, 106, 201, 202, 301, 311, and 315 airplanes, certificated in any category; serial numbers 003 through 598 inclusive. Unsafe Condition
(d) This AD was prompted by a report of a leak in the static pressure system, which could result in loss of the static systems and consequent erroneous data displayed on the pilot's flight instruments. We are issuing this AD to advise the flightcrew of applicable procedures in the event of abnormal indications of airspeed, altitude, or vertical airspeed; and to prevent leaks in the static system, which could result in the loss of critical flight information that could result in reduced controllability of the airplane or controlled flight into terrain. Compliance
(e) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Revision to Airplane Flight Manual
(f) Within 10 days after the effective date of this AD, revise the Normal and Abnormal Procedures sections of the applicable de Havilland Dash 8 Flight Manual to include the following statement in paragraph 4.11.1 of 4.11 PitotStatic and Stall Warning System Failures. This may be done by inserting a copy of this AD into the applicable flight manual.
``4.11.1 ABNORMAL INDICATIONS OF AIRSPEED, ALTITUDE AND VERTICAL AIRSPEED. 1. Appropriate STATIC SOURCE selectorALTERNATE. If switching the STATIC SOURCE selector to ALTERNATE does not correct the abnormal indications: 2. Rely on the flight instruments on the opposite side and land as soon as practicable.'' Note 1: When a statement identical to that in paragraph (f) of this AD has been included in the general revisions of the applicable flight manual, the general revisions may be inserted into the flight manual, and the copy of this AD may be removed from the flight manual. Modification of the Static System
(g) For airplanes having serial numbers 003 through 590 inclusive: Within 24 months after the effective date of this AD, modify the static system in accordance with Part A and Part C of the Accomplishment Instructions of Bombardier Service Bulletin 834221, Revision `A,' dated September 15, 2003.
(h) For airplanes having serial numbers 591 through 598 inclusive: Within 24 months after the effective date of this AD, modify the static system in accordance with Part B and Part C of the Accomplishment Instructions of Bombardier Service Bulletin 834221, Revision `A,' dated September 15, 2003.
Modifications Done According to Previous Issue of Service Bulletin
(i) Modifications done before the effective date of this AD in accordance with Bombardier Service Bulletin 834221, dated May 27, 2003, are acceptable for compliance with the applicable modifications specified in paragraphs (g) and (h) of this AD. Alternative Methods of Compliance (AMOCs)
(j) The Manager, New York Aircraft Certification Office, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested in accordance with the procedures found in 14 CFR 39.19. Related Information
(k) Canadian airworthiness directive CF200325, dated October 10, 2003, also addresses the subject of this AD. Material Incorporated by Reference
