Airworthiness Directive · Amendment 39-15578 · Fuel
Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135BJ Airplanes
Superseded. A later AD replaced this one: AD 2011-01-01. Comply with the one in force.
This AD applies to all EMBRAER Model EMB-135BJ airplanes, certificated in any category.
Note 1: This AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, the operator may not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (g) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions.
(1) The term “MPG,” as used in this AD, means the EMBRAER Legacy BJ—Maintenance Planning Guide (MPG) MPG-1483, Revision 5, dated March 22, 2007.
(2) Before December 16, 2008, revise the ALS of the ICA to incorporate Section A2.5.2, Fuel System Limitation Items, of Appendix 2 of the MPG. For all tasks identified in Section A2.5.2 of Appendix 2 of the MPG, the initial compliance times start from the applicable times specified in Table 1 of this AD; and the repetitive inspections must be accomplished thereafter at the interval specified in section A2.5.2 of Appendix 2 of the MPG, except as provided by paragraphs (f)(4) and (g) of this AD.
| Description | Compliance time (whichever occurs later) | Threshold | Grace period |
|---|---|---|---|
| 28-11-00-720-001-A00 | Functionally Check critical bonding integrity of selected conduits inside the wing tank, Fuel Pump and FQIS connectors at tank wall by conductivity measurements | Before the accumulation of 30,000 total flight hours | Within 90 days after December 16, 2008 |
| 28-13-01-720-002-A00 | Functionally Check Aft Fuel tank critical bonding integrity of Fuel Pump, FQGS and Low Level SW connectors at tank wall by conductivity measurements | Before the accumulation of 30,000 total flight hours | Within 90 days after December 16, 2008 |
| 28-15-04-720-001-A00 | Functionally Check Fwd Fuel tank critical bonding integrity of Fuel Pump, FQGS and Low Level SW connectors at tank wall by conductivity measurements | Before the accumulation of 30,000 total flight hours | Within 90 days after December 16, 2008 |
| 28-21-01-220-001-A00 | Inspect Wing Electric Fuel Pump Connector | Before the accumulation of 10,000 total flight hours | Within 90 days after December 16, 2008D |
| 28-23-03-220-001-A00 | Inspect Pilot Valve harness inside the conduit | Before the accumulation of 20,000 total flight hours | Within 90 days after December 16, 2008 |
| 28-23-04-220-001-A00 | Inspect Vent Valve harness inside the conduit | Before the accumulation of 20,000 total flight hours | Within 90 days after December 16, 2008 |
| 28-41-03-220-001-A00 | Inspect FQIS harness for clamp and wire jacket integrity | Before the accumulation of 20,000 total flight hours | Within 90 days after December 16, 2008 |
| 28-46-02-220-001-A00 | Aft Fuel Tank Internal Inspection: FQGS harness and Low Level SW harness for clamp and wire jacket integrity | Before the accumulation of 20,000 total flight hours | Within 90 days after December 16, 2008 |
| 28-46-04-220-001-A00 | Fwd Fuel Tank Internal Inspection: FQGS harness and Low Level SW harness for clamp and wire jacket integrity | Before the accumulation of 20,000 total flight hours | Within 90 days after December 16, 2008 |
(3) Before December 16, 2008, or within 90 days after the effective date of this AD, whichever occurs first, revise the ALS of the ICA to incorporate items 1, 2, and 3 of Section A2.4, Critical Design Configuration Control Limitation (CDCCL), of Appendix 2 of the MPG.
(4) After accomplishing the actions specified in paragraphs (f)(2) and (f)(3) of this AD, no alternative inspections, inspection intervals, or CDCCLs may be used unless the inspections, intervals, or CDCCLs are part of a later revision of Appendix 2 of the MPG that is approved by the Manager, ANM-116, FAA, or ANAC (or its delegated agent); or unless the inspections, intervals, or CDCCLs are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (g) of this AD.
Note 2: This AD differs from the MCAI and/or service information as follows: (1) The MCAI specifies a compliance date of “Before December 31, 2008” for doing the ALI revisions. We have already issued regulations that require operators to revise their maintenance/inspection programs to address fuel tank safety issues. The compliance date for these regulations is December 16, 2008. To provide for coordinated implementation of these regulations and this AD, we are using this same compliance date in this AD. (2) The MCAI specifies a compliance time of 180 days to revise the ALS of the ICA to incorporate items 1, 2, and 3 of Section A2.4 of Appendix 2 of the MPG. This AD requires a compliance time of 90 days to do this revision. This difference has been coordinated with ANAC.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
