Q & A: 
Question of the Week
For EAA Aviation Services

I am getting ready to paint my aircraft and was looking for an interpretation for the FAA N-number rules. Is it still permissible to taper the N-number in such a way as the "N" is the largest, and the ending digit/letter is still at least 12 inches high, but shorter than the "N", or do all letters and digits have to be the same height?

In order to understand the regulations regarding the registration marks (aka: "N-numbers") on aircraft, we need to take a look at 14 CFR Part 45. The specific answer to your question is found in 45.29, Size of Marks, which states in pertinent part:

(b) Height. Except as provided in paragraph (h) of this part, the nationality and registration marks must be of equal height...

Note that this regulation requires the characters of the registration mark to be of equal height, which would not allow the tapered numbers you suggest.
You can view the entire part 45 here

Proposed AD to Affect T-34 and Navion Owners
EAA is exploring ways to limit the impact of a proposed Airworthiness Directive that would affect T-34 and Navion aircraft equipped with McCauley propellers. The proposed AD comes as a result of tests conducted by McCauley that identified a high-stress condition that reduces the fatigue life and damage tolerance of these propellers when installed with certain engines. The stress condition, if left unaddressed, could result in blade or hub failure and result in separation of a propeller blade and subsequent loss of control of the airplane.

EAA Offers Oshkosh Flights in B-17 Bomber
EAA is offering a rare opportunity for local residents to fly in a historic World War II bomber on Sunday, December 4, when the Boeing B-17 Fuddy Duddy will host flight experiences from Wittman Regional Airport in Oshkosh. The flights, held in conjunction with EAA’s annual B-17 Fantasy Flight Camp, are the only local opportunities for B-17 missions this year outside of the annual EAA AirVenture fly-in. These opportunities are the same as those offered during EAA’s national B-17 tours each year, where thousands of people have experienced air travel in this aircraft, one of only about a dozen of the more than 12,000 B-17s built that are still airworthy.

EAA Insurance Tip --
Can You Handle an Emergency?
By Bob Mackey
Falcon Insurance Agency, Inc.
In the past week alone, we’ve seen two outstanding examples of skilled pilots and crewmembers handling in-flight emergencies. A few days ago we watched on live TV as a pilot brought a crippled Beech King Air in for a gear up landing with minimal damage and no injuries. Not long after that we heard about another pilot and crew in a Gulfstream G-V who worked through the challenges of a main gear that would not lower to successfully and safely land the aircraft with all gear down and no damage or injuries. Was this luck? I believe it all comes from one key factor: training. The pilots and crew worked through their situations, employed their training, and performed as professionals.

Special Airworthiness Information Bulletin for Lycoming Engines
A potential assembly problem on Lycoming four and six cylinder, dual magneto engines with rear mounted propeller governor drives could result in loss of engine oil leading to an engine failure. The oil loss results from the omission of a plate, Lycoming part number (P/N) LW-12347, which is required between the propeller governor drive pad and the propeller governor. The plate is only 0.040 inches thick and could be mistaken for a used gasket and discarded with removal of the propeller governor or shipping cover. The plate is actually a spacer to position the propeller governor away from the propeller governor drive pad. Without it, the propeller governor shaft might make contact with the bottom of the gear assembly inside the rear accessory case and prevent the propeller governor drive pad and the propeller governor flange from being drawn together to compress the gaskets. If the gaskets aren’t compressed, they will not form a sufficient seal, which could cause an oil leak.
