Airworthiness Directives; British Aerospace Jetstream Model 3101 
Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Direct final rule; confirmation of effective date.

-----------------------------------------------------------------------

SUMMARY: This action confirms the effective date of Airworthiness 
Directive (AD) 98-12-31, which applies to certain British Aerospace 
Jetstream Model 3101 airplanes. AD 98-12-31 requires repositioning the 
fuel cross feed pipes in the lower center fuselage to give an overall 
clearance of 2 inches when measuring from the bottom of Frame Station 
223. This AD was the result of mandatory continuing airworthiness 
information (MCAI) issued by the airworthiness authority for the United 
Kingdom. The actions specified in this AD are intended to prevent the 
fuel pipe from fracturing during a wheels up landing because of the 
positioning of the fuel cross feed pipes, which could result in an 
airplane fire.

EFFECTIVE DATE: September 10, 1998.

Engineer, FAA, Small Airplane Directorate,

SUPPLEMENTARY INFORMATION: The FAA published this direct final rule 
with request for comments in the Federal Register on June 12, 1998 (63 
FR 32121). The FAA uses the direct final rulemaking procedure for a 
non-controversial rule where the FAA anticipates that there will be no 
adverse public comment. This direct final rule advised the public that 
no adverse comments were anticipated, and that unless a written adverse 
comment, or a written notice of intent to submit such an adverse 
comment, was received within the comment period, the regulation would 
become effective on September 10, 1998. No adverse comments were 
received, and thus this notice confirms that this final rule will 
become effective on that date.

    Issued in Kansas City, Missouri, on July 28, 1998.

This packet is not an airworthiness determination and not legal or maintenance advice. AircraftDirectives reproduces official records and condenses their wording for easier reading. It does not decide, certify or imply whether any aircraft, engine, appliance or part is airworthy, compliant, affected by this directive, or eligible for return to service. No inspection, approval, or determination of any kind is performed or implied by this document.

Section 1 is a reading aid, not the rule. It is our own plain-language condensation, written to help a reader find the relevant directive quickly. It is NOT a substitute for the regulation, it may omit conditions, exceptions, compliance times, alternative methods of compliance (AMOCs) and applicability limits, and it has no legal force whatsoever. Only the official text governs. Where Section 1 and Section 2 differ in any respect, Section 2 - and the official source it was retrieved from - controls absolutely.

Responsibility remains with the owner/operator. Under 14 CFR §91.403 and §91.417 the owner or operator is responsible for maintaining airworthiness and for required records; under §39.7 no person may operate a product to which an airworthiness directive applies except in accordance with that directive. Determining applicability to a specific serial number and configuration, and performing or supervising any required action, is the responsibility of the owner/operator and appropriately certificated personnel.

Accuracy and currency. Section 2 was retrieved at the time stamped above and is reproduced without edit; Federal Register material is a work of the United States Government. Directives are amended, corrected and superseded over time, and this sheet is a snapshot, not a live record - it does not update after printing. Re-check the official sources before acting on it. This packet is provided without warranty of any kind, express or implied, including fitness for a particular purpose. We do not sell parts and have no commercial interest in any action a directive may require.
