Applicability:

Cessna Model 560 model aeroplanes with serial numbers 0001 through 0648 inclusive.

Requirement:

1. If not previously accomplished, revise the Limitations Section of the applicable Cessna aircraft flight manual (AFM) to prohibit use of the wing fuel boost pumps for defueling under certain conditions, by inserting the applicable temporary change identified in the following table.

2. If not previously accomplished, install a placard close to the fuel quantity gauge, in accordance with the Accomplishment Instructions of the Cessna Service Bulletin SB560-28-10 dated 23 April 2004 or SB560-28-11 dated 12 March 2004, as applicable. In addition to the specifications in the service bulletin, the letters on the placard must be at least 6mm (1/4 inch) tall.

3. If not previously accomplished, carry out the following action in accordance with the Accomplishment Instructions of SB560-28-10 or SB560-28-11, as applicable:

a. Do a detailed inspection for chafed wiring of the wing fuel boost pumps.

b. Modify the wing fuel boost pumps.

\n```\n\n| | Note 1: For the purposes of this Directive, a detailed inspection is: \"An intensive examination of a specific item, installation or assembly to detect damage, failure or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.'' |\n| ----------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| | 4. If as a result of the Requirement 3.a. inspection and discrepancies are detected accomplish all applicable corrective and other specified actions in accordance with the applicable service bulletin. |\n| | 5. Remove the Requirement 1 AFM temporary change and the Requirement 2 placard. |\n| | Later revisions of the above SBs, approved by the United States Federal Aviation Administration (FAA) as an Alternate Method of Compliance (AMOC) to FAA AD 2006-05-08, are considered acceptable for compliance with the equivalent Requirements of this Directive. |\n| | Note 2: FAA AD 2006-06-03 Amdt 39-14511 refers. |\n| Compliance: | For Requirements 1 and 2 - Within 25 hours time in service (TIS) after the effective date of this Directive. |\n| | For Requirement 3 - Within 300 flight TIS after the effective date of this Directive. |\n| | For Requirement 4 - Before further flight, immediately following the Requirement 3.a. inspection. |\n| | For Requirement 5 - Before further flight after the Requirement 3 inspection and modification are accomplished. |\n| | This Airworthiness Directive becomes effective on 20 April 2006. |\n| Background: | This Directive requires the revision of the AFM to initially prohibit use of the wing fuel boost pumps for defueling under certain conditions and the installation of a placard. The Directive subsequently requires the accomplishment of other specified investigative and corrective actions as necessary. Terminating action for this Directive is the modification of the wing boost pumps together with the removal of the AFM revision and placard. |\n\n| | The FAA has received a report of a chafed electrical wiring harness, which was arcing inside the fuel tank. This Directive is issued to prevent potential fuel vapour ignition in a fuel tank, which could result in explosion and loss of the aeroplane. |\n| --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n\n![](image.001.png) \nJames Coyne \nDelegate of the Civil Aviation Safety Authority\n\n4 April 2006","sortOrder":0},{"sectionNumber":"AD/CESSNA 560/8","sectionType":"part","heading":"AD/CESSNA 560/8","content":"## AD/CESSNA 560/8","sortOrder":1},{"sectionNumber":"Wing Fuel Boost Pumps","sectionType":"part","heading":"Wing Fuel Boost Pumps","content":"## Wing Fuel Boost Pumps","sortOrder":2},{"sectionNumber":"6/2006 DM","sectionType":"part","heading":"6/2006 DM","content":"## 6/2006 DM","sortOrder":3}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
