SAIB: CE-13-45 Engine Exhaust; Tailpipe V-band Couplings

This Special Airworthiness Information Bulletin (SAIB) informs owners, operators, and maintenance personnel of turbocharged, reciprocating engine-powered airplanes about the potential for in-flight fire as a result of failure of the exhaust system V-band coupling securing the tailpipe to the turbocharger, the wastegate overboard, or any other exhaust system V-band coupling.

The FAA has issued airworthiness directives (AD) in the past concerning V-band couplings for specific airplane models. These ADs remain in effect where applicable. For those airplanes not affected by a V-band coupling AD, this airworthiness concern is not considered an unsafe condition at this time that would warrant AD action under Title 14 of the Code of Federal Regulations, part 39.

AD 2013-09-11Smoke and/or fire in the tailcone

We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company Model 500, 501, 550, 551, S550, 560, 560XL, and 650 airplanes. This AD was prompted by multiple reports of smoke and/or fire in the tailcone caused by sparking due to excessive wear of the brushes in the air conditioning (A/C) motor. This AD requires inspecting to determine if certain A/C compressor motors are installed and to determine the accumulated hours on certain A/C drive motor assemblies; repetitive replacement of the brushes in the drive motor assembly, or, as an option to the brush replacement, deactivation of the A/C system and placard installation; and return of replaced brushes to Cessna. We are issuing this AD to prevent the brushes in the A/C motor from wearing down beyond their limits, which could result in the rivet in the brush contacting the commutator causing sparks and consequent fire and/or smoke in the tailcone with no means to detect or extinguish the fire and/or smoke.

AD 2013-08-05 Cessna 525 Air conditioning compressor motors

We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft
Company (Cessna) Model 525 airplanes equipped with certain part number (P/N) air conditioning
(A/C) compressor motors. This AD was prompted by reports of smoke and/or fire in the tailcone
caused by brushes wearing beyond their limits on the A/C motor. This AD requires inspection of the
number of hours on the A/C compressor hour meter, inspection of the logbook, replacement of the
brushes on certain P/N A/C compressor motors or deactivation of the A/C system until replacement
of the brushes, and reporting of airplane information related to the replacement of the brushes. We
are issuing this AD to correct the unsafe condition on these products.

FAA-2012-18033 Inboard aileron hinge brackets

We are revising an existing airworthiness directive (AD) for all Cessna Aircraft Company (Cessna) Models 190, 195 (L-126A,B,C), 195A, and 195B airplanes that are equipped with certain inboard aileron hinge brackets. That AD currently requires you to repetitively inspect the affected inboard aileron hinge brackets for cracks or corrosion and replace them if cracks or corrosion is found. Replacement with aluminum brackets would terminate the need for the repetitive inspections. This new AD retains the actions of AD 2004-21-08 while requiring future compliance following a revised service bulletin that clarifies the casting numbers and part numbers to be inspected. This AD was prompted by reports of confusion between the casting number on the aileron hinge bracket and the part number (P/N) called out in the AD. We are issuing this AD to correct the unsafe condition on these products.

SAIB: CE-13-27 Flight Controls – Frayed Flap Extend Cables

This Special Airworthiness Information Bulletin (SAIB) is intended to remind owners and operators of any airplane with cable-driven flight controls of the importance of adhering to existing inspection procedures in the applicable maintenance or shop manuals.
At this time, this airworthiness concern is not considered an unsafe condition that would warrant airworthiness directive action under Title 14 of the Code of Federal Regulations (14 CFR), part 39.

SAIB: Electrical Power System – Circuit Breaker Switch

This Special Airworthiness Information Bulletin (SAIB) advises owners and operators of various airplanes equipped with W31 series switch style circuit breakers (SSCB) manufactured by Tyco or Potter Brumfield of an airworthiness concern.

Specifically, there have been known continued failures of these SSCBs on Cessna Aircraft Company airplanes and Beechcraft Corporation (formerly known as Hawker Beechcraft Corporation) airplanes.
These circuit breaker switches may also be installed on other type certificated airplanes as well as homebuilt airplanes.

The Perfect 10: Aircraft Interiors: Tips and suggestions from SCS Interiors

March 2013-

Freshening up your aircraft’s interior can be an important update for many reasons. In addition to looking good, it increases your and your passengers’ comfort. New carpet and seat coverings often add value to your aircraft while reducing cockpit noise and vibration.

Many pilots dream of the day their airplane’s cockpit is a Perfect 10, and for many, leather seats are at the top of the wish list. “There is nothing more beautiful than a leather interior in a plane—especially one that is custom designed in colors to give the plane a ‘total package’ look,” said Mike Hudyma, Vice President of SCS Interiors (“Style-Comfort-Security”) in Duluth, Minn.

Additional features that add beauty to a plane interior are the amenities such as leather armrests, yoke controls, door handles and similar items which are hand-stitched.

Certification requirements

All materials utilized in any interior products must meet the FAA’s flammability requirements.

“Occasionally we will have a customer who asks why the carpet for his plane costs more than something he could buy at his local carpet market,” said Hudyma. “Besides the customization in cutting the carpet to the template of a specific aircraft, SCS Interiors must provide carpet—or vinyl flooring—which meets specific FAA burn certification standards.”

“In addition, the selection of the appropriate materials for flooring requires consideration of a durable product but also one that is not too heavy. Often pilots want to add noise-dampening materials under the carpet. These materials are usually very lightweight—but effective—and together with the carpet provide a quieter ride by reducing vibration and noise.

“Depending on the model of the aircraft, additional carpet may also be sewn on side panels. As a pilot considers the total weight of their aircraft, the flooring will be a part of the weight, which may result in less fuel being loaded—thus, less flying,” Hudyma continued.


For DIY-ers

Attention to detail is key for a do-it-yourself installation. “It’s important to remove the old carpet and properly prepare the surface for the new installation. This is a good time to remove potentially dangerous debris as loose particles will make adhesion difficult for whatever bonding material is utilized for the new carpet,” Hudyma explained.

A typical installation uses Velcro and contact cement. “SCS Interiors’ kits come with the necessary Velcro,” said Hudyma.

Pre-cut kits for a Cessna 172 (models N-P) aircraft are priced at $395 for carpet and $645 for vinyl on the SCS Interiors website, and many Cessna models are available. SCS also offers floor mats, wing mats, cargo area mats, cleaning products and accessories.

SCS Interiors has been serving the aerospace industry for more than 15 years, so they know their customers. “We know pilots love any opportunity to fly in beautiful weather,” said Hudyma, “and many like the added comfort of a sheepskin seat cover which provides warmth in the winter and coolness in the summer.”

And they also know that pilots fly with their pets, so they’ve developed a product for those four-legged family members. “Fido may also like to have his own comfort mat if he is enjoying the plane trip, too,” said Hudyma. SCS Interiors provides carpet doggy mats for man’s best friend.

SCS Interiors’ owners David Hudyma, a military veteran, and his son, Mike Hudyma, have guided the company through several expansions to its current state-of-the-art facility in Duluth. The 40-year-old company’s custom interior products are designed, developed and manufactured in Minnesota—truly, made in the USA.

FAA-2012-1273 Fuel return line assembly

We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft
Company Models 172R and 172S airplanes. This AD was prompted by reports of chafing of a new
configuration of the fuel return line assembly, which was caused by the fuel return line assembly
rubbing against the right steering tube assembly during rudder pedal actuation. This AD requires you
to install the forward and aft fuel return line support clamps and brackets; inspect for a minimum
clearance between the fuel return line assembly and the steering tube assembly and clearance
between the fuel return line assembly and the airplane structure; and, if any damage is found, replace
the fuel return line assembly. We are issuing this AD to correct the unsafe condition on these

Ladies, Start Your Engines: Air Racing for your “Sunday Sedan”

November 2012

Ladies, Start your engines!

Every June over 100 female pilots come together to participate in the four-day, 2,500-mile, cross-country, VFR, all-women’s Air Race Classic, the modern-day continuation of the Powder Puff Derby.


These pilots do not arrive in highly modified experimental aircraft. Quite the contrary: they race their every day, average, stock airplane—their “Sunday Sedan.” The Air Race Classic rules even prohibit entry of experimental aircraft for competition.

Basically, if your airplane is a commercially manufactured single or twin, is normally aspirated, has no restrictions on running continuous full power and can make each race leg in its entirety without fueling, your plane is probably qualified to race.

Many, if not most, of the race airplanes from the 2012 race were Cessnas. Fifteen of the top 16 finishing planes were Cessnas.

So what does it take to race your stock Cessna in a four-day cross-country race?

First and foremost, know your airplane. Even if you rent a plane for the race, know your airplane. Make sure you have a good feel for the aircraft at normal cruise speed.

Sennheiser S1 Headset Pirep

November 2012

 Recently I flew with my friend Dean in his straight-tail Cessna 172. I was photographing our friend’s newest airplane, so I opened the window. This rather large opening created lots of fresh air. And lots of wind noise.

Dean and I just shouted back and forth to each other (cross-cockpit, that is) to communicate. Even though it was a relatively short flight, I could feel that my vocal chords were strained after we landed.

Now I am climbing out as the pilot a larger aircraft, which obviously creates a greater amount of wind noise than in Dean’s 172. I never realized how loud it was in this cockpit, either, until I donned my new Sennheiser Digital S1 headset. All that air rushing up over the nose of my plane has been reduced to what sounds like a very light breeze.

After turning on the headset’s active noise reduction, it gets even more unbelievably quiet in the cockpit. With ANR canceling out all of the unwanted noise, I’m able to hear other, more important things. Like the radios.

With a Sennheiser S1, I can listen to the ATIS while still monitoring the active ATC frequency. I was not able to do this in the past—with other headsets, that is. Before, I would always have to completely turn down one of the radios to hear the other radio. This headset is so quiet that all I hear is the beginning and end of the trim motor engagement.
