Maintenance Checks - Bell 407

Posted by jhadmin

The 407 intake cowl assembly is notorious for corroding in salt-laden environments, especially on the intake shelf and intake screen supports. One proactive measure is to remove the shelf and screen support associated steel nut plates, strip the factory paint, and apply a new coat of epoxy primer and a quality polyurethane paint. Then reinstall the nut plates with dissimilar metal tape between the nut plates and aluminum metal. The result won’t be 100% corrosion proof, but will make it much easier to manage. [Read More...]

Executive Watch - Boeing Global Services Senior Manager of Helicopter Operations - Ty Genteman

Posted by jhadmin

It was a no-brainer for Boeing Global Services Senior Manager of Helicopter Operations Ty Genteman to get into the aviation industry—or more accurately—it was a no-brainer for him to get out of the blistering desert heat. He was pulling cable in his telecom construction business when a friend called with a simple proposition. Genteman clearly recalls the 1986 conversation that changed his life. His friend, Eric Witters, made his pitch, “It’s July in Arizona and you’re working in 118 degrees; how would you like to come to Aviall and get out of the heat?” [Read More...]

Maintenance Minute - EC135 Blue Light Special

Posted by jhadmin

Troubleshooting an intermittent yaw caution light with the autopilot and FCDS installed can be a pain sometimes. Since both the yaw SAS SEMA and the yaw autopilot SEMA are mounted on the same control tube at the Fenestron, the yaw SEMA 1 can influence yaw SEMA 2, or vice versa. The trick is to separate the systems by turning off the autopilot and pulling into hover; if the yaw light indication returns, it should be the yaw SEMA 2. If not, it should be yaw SEMA 1.

Maintenance Minute - Go Go Juice

Posted by jhadmin

No, we’re not talking about a slow-speed chase down a California highway; rather, your lost and sometimes forgotten aircraft battery. Without it, your day will never properly start. With the advent of improved technology, lead-acid batteries are becoming more commonplace in turbine-powered helicopters. And while lead-acids have certain advantages over the original NiCad batteries, a number of “operational” differences could reduce the effect and value of those advantages. [Read More...]

One Man's Trash

Posted by jhadmin

After a recent helicopter accident, some old topics popped up on a number of internet forums: aircraft repairs, aircraft data plates, and salvage parts. While it remains to be seen if any previous repairs have fault in this accident, the ensuing discussions demonstrated that there is an ongoing knowledge gap in how aircraft repairs can be performed legally. First, the use of aircraft salvage parts in aircraft repairs is perfectly legal within the FARs and is a classic example of, “One man’s trash is another man’s treasure.” However, when it comes to data plates, there is – and has been – specific regulatory guidance on how they are made, attached, and maintained. Unfortunately, some people are not aware of (or choose not to follow) this FAA guidance. As such, the FAA and the OEMs have become more proactive in this area in recent times. For instance, as recently as October 2018 the FAA issued new guidance. So follow below as we continue the discussion. [Read More...]

Maintenance Minute - All Torqued Up

Posted by jhadmin

Ever get all torqued up reading a helicopter maintenance manual because you couldn’t remember the difference between a re-torque and a torque check? I did, until I had their definitions tattooed on my — well, that’s another story. In the meantime, let’s work out their definitions here. Because not understanding the difference between a “re-torque” and a “torque check” can lead to potentially disastrous consequences. [Read More...]

Maintenance Minute - Blue Light Special 3

Posted by jhadmin

String-aligning Bell 206 M/R blades can be a bit tedious. To help see the string better, fabricate a couple stringing mirrors. You can use pieces from a broken mirror or buy a couple small rectangular mirrors that will sit across the top of the M/R blade bolt. [Read More...]

Maintenance Minute - SCREWED

Posted by jhadmin

SCREWED! Stuck screws. What a pain! But before you drill the screw head off, here are a few tips to try. This is mainly for Phillips style screws, but can be adapted to other types. First, clean out the “cross” recess area. Use an awl or pick if necessary. Any debris like paint, dirt, or rust will prevent the driver tip from fully seating into the cross. If the tip is not seated correctly, it will damage the recess drive areas on the first attempt. If the screw is buried under a layer of paint, remove the paint from the entire screw head area. Be sure to select the correct driver bit or screwdriver. A Reed & Prince #2 bit will strip out a Phillips #2 screw head and vice versa. Ensure the bit or driver tip is not worn smooth. If possible, use bits with serrations on the drive flanges. [Read More...]

WHO’S ON FIRST… THE OWNER OR THE MECHANIC?

Posted by jhadmin

In aviation, there are some topics that never seem to remain settled. For instance, does the responsibility for the inspection and maintenance of an aircraft fall to the owner/operator or the mechanic? Simple. The owner or operator. However, this hierarchy still gets twisted around occasionally. The reasons vary on both sides of the fence. They range from simple misinformation or misinterpretation of the FARs to intentional motives in pursuit of an external agenda. Follow along as we delve into the available guidance and provide a balanced, one-stop-shop approach to who’s in charge of maintaining an aircraft. [Read More...]
