Overview

In 1985 AC discontinued production of the popular “RT” series of mechanical tachometers. Mitchell immediately entered the market to fill the void. These tachs feature exceptional accuracy and reliability. Mitchell tachs come with a factory-direct 2 year warranty. The range on all models is 500 to 3500 RPM. Accuracy is +/- 25 RPM from 1000 to 3000 RPM. Determine the correct part number from the chart below. All Mitchell tachs are FAA approved to TSO-C49b for certified aircraft.

2-1/4" tachs are direct replacements for the 3-1/8" tachs to save panel space.

10-02354 for custom range marks (specify ranges, 4-6 week lead time).
10-02479 to set hours (specify hours, 14 day lead time).

Direction of rotation is defined as when viewing the front of the tachometer.

MITCHELL TACHOMETER D1-112-5023

September 15, 2023

My current tach froze this morning at 1600 RPM. Needless to say I was stuck (pun intended). Susan and the team at Mitchell Aircraft helped me diagnose and resolve my problem. They worked with me to get a new tach in the process as quickly as possible. Anyone with an aircraft knows downtime is the norm. But, if there is someone kind and helpful like Susan was today. They can get you back in the air safely and faster. I appreciate their help and will recommend all my fellow aviators that they use Mitchell whenever possible.
