P&W Portable Video Borescope Inspection Kit is the Best Option for an Aviation Borescope

by | Jun 23, 2022 | News

Borescope inspection systems are popularly used in various industries because they are so small, multi-purpose and can help identify crucial errors. Even in the aviation industry, borescope kits are widely used for helicopter maintenance, aircraft engine checkup as well as for the landing gear.

USA Borescope Applications for Pratt & Whitney Engines

The 3 largest providers of aviation and helicopter engines are Pratt & Whitney, GE Engines and Rolls Royce engines and these engines are used throughout the world in both military, commercial and business jet engines. The Pratt & Whitney engines are very popular in business jet engine applications. Over ¼ of the entire passenger air vessels are equipped with Pratt and Whitney engines. Most of these engines come from the Pratt & Whitney facility in Canada.

USA Borescopes provides borescope that are designed to complete the Pratt & Whitney Borescope inspections. Most all of these engines will require an articulating borescope to complete the inspection. Articulating borescopes allow the borescope inspector to manipulate the probe tip to visually inspect each turbine blade and confirm airworthiness. Aviation engine inspections keep these precision-made engines at top performance and minimizes unscheduled downtime. And of course, airplanes do not make money on the ground so keeping these engines operational and safe is critical.

As videoscope cameras continue to advance in technology and features you can be assured that the demand to save both time and money while increasing image quality will be of high demand. USA Borescopes will continue to provide and support our world class borescope products and we invite you to test out our quality and responsive customer service.

Given this factor and its usability and portability, it is no surprise the P&W portable video borescope inspection kit is a favorite among aviation borescope professionals. The kit may be small in size but it delivers powerful results and can be used in different vehicles, including helicopters and planes without any issues.

The P&W portable video borescope inspection kit has a videoscope system that delivers high quality imagery and video results. The bore camera is 4mm in diameter and encased in a durable tungsten sheath that prevents it from damage. It also has a 2 or a 4-way articulation system that improves its flexibility and range of use.

It comes with a 4.3-inch LCD screen, which is compact and easy to carry. All the data from the P&W portable video borescope inspection kit can be stored on an SD card and it also has video recording features. It also has built-in LED lights to deliver better images and clarity in videos.

A major reason behind the popularity of the P&W portable video borescope inspection kit is the fact that it is perfect for the inspection of aircraft engines, such as the PT6. The P&W portable video borescope inspection kit can also be used on automotive engines, making inspection easier. It is also compatible with different Borescope guide tubes, namely, the PWC34910-400, the PWC34910-200 and the PWC34910-600.

The P&W portable video borescope inspection kit is neatly encased in a hard plastic, heavy-duty storage case that makes sure that the kit does not get damaged when it is carried around. The P&W portable video borescope inspection kit is available at different retailers. Prices can vary based on whether you opt to get a 2 or a 4-way articulation system.

The original PWC34910-109 borescope inspection kit as well as the PWC34910-108 Borescope inspection kit as listed in the Pratt & Whitney Service letter S.I.L NO. GEN- PT6-029 specifically referred to a fiberscope kit. However, with the advances in technology videoscopes entered the scene and are now the dominate visual inspection device used for these Pratt & Whitney engine inspections. Although most people refer to this visual inspection cameras as a borescope for either of those devices. Some other common references to these products are borascopes, bore scopes, video borescopes or borescope inspection camera.

These models listed on the Pratt & Service letter were actually tested by Pratt & Whitney Engineers. Those suppliers include: Olympus, GE and the now closed suppliers of Machida and Borescopesrus. Both BorescopeRus and Machida Borescope have systems out in the field and very well may be performing well or you may find one for sale on Ebay. Either way if you require a repair of your Borescopes R Us (or Borescopes Rus or BorescopesR Us) borescope or your Machida borescope we encourage you to contact www.borescope-repair.com.

Pratt & Whitney No Longer provides approval of specific borescope or videoscope suppliers as the internet and targeted marketing have given borescope users more options to consider. The most popular diameter for Pratt and Whitney borescope inspections is the 4mm diameter borescope. Keep in mind that borescopes that range in diameter from 3.7 and up to 4.5mm in actual diameter will be included as a 4mm borescope. With that in mind, there are some 5mm diameter borescope that will perform acceptably in some of the P&W Guide tubes as well.

The key point to remember is that what is important is that the videoscope being used meets or exceed the requirements as listed in the Pratt & Whitney service letter. Maximum diameter of 4.3 mm and minimum probe length are easily achieved with the PWKit 2 and the PWKit 4. Both of these systems meet or exceed the requirements of the PWC34910-109 borescope kit. Of course, at the time of the Pratt & Whitney service letter S.I.L NO. GEN- PT6-029 two-way articulation was the most widely used when it came to borescope products. Again, with the advances in technology and features four way and joystick articulation are the most popular. Picture taking and video recording of the turbine inspection are perfumed with the touch of a button. Conversely, image capture and video recording with the older fiberscopes required external cameras and light sources. This was a very cumbersome process especially if you were on an elevated platform. As stated earlier, the new borescope models provide on board image capture and video recording capabilities which is a significant improvement over the older fiberscope models.

This borescope kit has been found especially useful for the inspection of Pratt & Whitney PT6 engines, highlighting the unit’s small diameter, short distal ends in order to easily navigate through the PWC34910-200, PWC34910-400, PWC34910,600 borescope guide tubes, as well as many others.

Machida borescopes for many years was a leader in the Pratt & Whitney approved borescopes and unfortunately, they ceased operation many years ago. These Pratt & Whitney approved borescopes meet the requirements as outlined in the Pratt & Whitney Service letter and these borescopes meet or exceed these requirements. For many years these Pratt & Whitney borescopes served the aviation and aerospace inspectors with quality products.

In addition, there are other Pratt & Whitney approved borescopes listed that have similar or slightingly different specifications. P&WC EMM also refers to the borescope kits:

PWC37711 Borescope

PWC38711 Borescope

PWC90236 Borescope

PWC34910-101 Fiberscope

PWC34910-106 Fiberscope

PWC34910-107 Borescope

PWC34910-108 Borescope

PWC34910-109 Borescope

To our knowledge there aren’t any other borescope kits listed on the old Pratt & Whitney Service Letter list nor an updated list. Keep in mind, this service letter is now more than 10 years old and a lot of significant change has occurred in the borescope and videoscope industry since it’s release.

This videoscope kit meets the requirements to perform an HSI borescope inspection (hot section borescope) as described in the applicable EMM and P&WC SIL PT6A-116.

The Pratt & Whitney Canada PT6 Engine is a turboprop aircraft engine produced by Pratt & Whitney Canada. Its design was started in 1958, it first ran in February 1960, first flew on 30 May 1961, entered service in 1964 and has been continuously updated since. It consists of two basic sections: a gas generator with accessory gearbox and a free power turbine with reduction gearbox, and is often seemingly mounted backwards in an aircraft in so far as the intake is at the rear and the exhaust at the front. Many variants of the PT6 have been produced, not only as turboprops but also for helicopters, land vehicles, hovercraft, boats, as auxiliary power units and for industrial uses. By November 2015, 51,000 had been produced, had logged 400 million flight hours from 1963 to 2016. It is known for its reliability with an in-flight shutdown rate of 1 per 651,126 hours in 2016. The PT6A covers the power range between 580 and 1,940 shp (430 and 1,450 kW) while the PT6B/C are turboshaft variants for helicopters.

This portable videoscope is perfect for helicopter maintenance borescope for use as a Helicopter borescope as it can be used as a Helicopter Engine Borescope or helicopter airframe borescope. The same is true for Aviation borescope professionals; the portable borescope can be used as an aircraft engine borescope or simply as an aviation borescope for frame of landing gear inspections.
