It’s a nightmare scenario for any Twin Cessna owner: an uncontrollable fire breaks out mid-flight, the result of an insidious crack in the exhaust system.
Fuel-fed fires are a serious risk, and they’re the reason the FAA-issued Airworthiness Directive (AD) 2000-01-16 has strict inspection and repair requirements for Twin Cessna exhaust systems, including who can perform the necessary maintenance and when each component needs to be checked. Compliance with the directive helps to ensure that exhaust systems are in good condition and helps prevent life-threatening situations.
Fortunately, Double M Aviation is here to help with a high standard of maintenance, giving you greater confidence in your aircraft and peace of mind that your Twin Cessna exhaust system is being maintained the right way. Here are the details.
Components and Systems in AD 2000-01-16
AD 2000-01-16 prescribes a series of maintenance steps, including visual inspections, pressure testing, and part replacement. Here are some of the things your certified maintenance technician needs to do to keep your aircraft in compliance:
- Visually inspect the exhaust system.
- Remove and visually inspect the tailpipes.
- Inspect the engine beams and canted bulkheads.
- Inspect the fuel tubing behind the firewall if conditions call for it.
- Replace the fuel tubing if necessary.
- Remove the exhaust system for shipping to an FAA-approved facility for inspection.
- Conduct a repetitive pressure test.
- Replace the multi-segment V-band clamps.
Beyond the requirements, the FAA recommends other maintenance steps in certain conditions, such as checking the turbocharger wheel performance any time the tailpipe is removed to ensure there’s no excessive friction. The FAA also recommends inspecting the cables and the torque tag values on the single-piece V-band clamps.
When done by a certified aircraft technician with the proper skills and experience, the steps outlined in AD 2000-01-16 help prevent dangerous situations and keep the relevant systems in excellent condition.
A Certified Aviation Maintenance Technician Is a Necessity
It’s not enough to follow the Cessna service information and maintenance manual revisions. AD 2000-01-16 takes precedence, and it requires that certain maintenance tasks be performed by certified personnel.
Visual inspections should be done by an aviation maintenance technician with an A&P rating. Replacements should be done by a certified aircraft technician with an A&P rating or by someone authorized to represent an FAA-approved repair station.
When it comes time for more advanced exhaust system work, such as removal, coordination with an FAA-approved repair facility, and return-to-service documentation, using a certified aviation maintenance technician is essential. These tasks require the right credentials, close attention to AD 2000-01-16, and the experience to ensure the work is completed safely, correctly, and in full compliance.
Timeline for Compliance with AD 2000-01-16
As with most inspection and maintenance requirements, AD 2000-01-16 comes with a schedule. Here are the timing requirements Twin Cessna owners should keep in mind:
- Visually inspect the exhaust system every 50 hours or 30 calendar days (whichever is later).
- Remove and inspect the tailpipes every 12 months.
- Visually inspect the outboard engine beams, firewalls, and canted bulkheads every 500 hours of time in service (TIS).
- Inspect and pressure test the exhaust system every 12 calendar months.
- Replace the multi-segment V-band clamps every 500 hours TIS.
- Remove the exhaust system from the slip joints aft to all turbocharger components every 2,500 hours TIS or 12 years, whichever is first. (This coincides with your regularly scheduled engine overhaul.)
If damage is found on any component, that damage must be addressed before any further flight.
While any aircraft mechanic can look at an engine, it takes a specialized aircraft technician to manage the compliance tracking and labor-intensive overhauls required for these turbocharged systems.
Missing an inspection interval, overlooking a clamp replacement, or failing to track the 12-year/2,500-hour Paragraph (g) requirement can create both safety issues and compliance problems. At Double M Aviation, we take a manual-driven, documentation-first approach so nothing gets overlooked.
Double M Aviation is here to help you navigate the requirements for your Twin Cessna, minimize downtime, and maintain your peace of mind. Our team follows the aircraft maintenance manuals, service information, and AD requirements exactly as written.
Your Paragraph (g) Twin Cessna Exhaust System Overhaul
Paragraph (g) of AD 2000-01-16 calls for the removal of the exhaust system “from the slip joints and aft to all turbo-charger attached components.” The exhaust system is to be sent to an FAA-approved exhaust repair facility for inspection and any needed repairs.
While this may sound intimidating to some Cessna owners, the reality is that when the removal and handling are done by the experienced, certified aviation maintenance technicians at Double M Aviation, you can relax, knowing that your exhaust system—and your entire aircraft—are in the right hands.
The Double M Aviation Advantage
When it comes to AD 2000-01-16 compliance, experience matters, but specialized, licensed teamwork matters even more. Compliance with this directive is a labor-intensive process that demands careful handling, detailed documentation, and coordination with an FAA-approved exhaust repair facility.
At Double M Aviation, our specialized team knows Twin Cessna systems inside and out, so we complete every requirement efficiently. For example, Paragraph (g) removals can often be completed within five business days. That kind of turnaround can be difficult for a solo mechanic.
Just as important, exhaust system maintenance is no place to cut corners. AD 2000-01-16 exists because exhaust system defects can lead to fuel-fed fires and other serious in-flight hazards. The stakes are high. That’s why Double M Aviation uses only licensed aviation maintenance technicians who understand the risks, respect the requirements, and make safety their top priority.
