Crash test of a Cessna 172 light aircraft. The Cessna was dropped from 82 ft at the NASA Langley Impact Dynamics Research Facility. NASA's Search and Rescue Mission Office this week conducted the third and final Cessna 172 Skyhawk crash test at the NASA Langley Research Center in Hampton, Virginia, in its quest to improve. Too great a drop in rpm can be an indication of several problems - anything from a fouled plug to a bad ignition wire to improper timing to a bad magneto. It needs to be checked . To clarify what I believe is correct, if during your run up you raise power to 1700 rpm and do your mag check, turn to left mag good drop, back to both, then right mag and you .
If one spark plug is fouled or failed the temperature will drop rapidly in that cylinder when tested. Read the monitor to find the cylinder affected and remove the spark plug attached to the magneto affected.

The drop is slightly greater on R than on L, but within the 50 rpm between limit. The POH also says that repeating the test with leaner mixtures or at higher rpms will "confirm whether a deficiency exists". So as instructed by my A&P, I have been repeating the test with the mixture leaned out close to peak, and there the rpm drop is only 100 . A voltage drop test will assess voltage losses at the battery, the alternator and the starter. Part 1: Battery. 1) With the voltmeter connected to battery, and key and engine off, record a "base" voltage reading. (Your battery should have a minimum of 12.4 volts.) If it is less than 12.4 volts, charge the battery and repeat the test.
Smooth operation of the engine but with a drop-off that exceeds the normal specification of 175 RPM is usually a sign of propeller load condition at a rich mixture. Proceed to step E.(1)(d)." (Looks like the drop off limit is now 175 instead of 150) 3) "If the RPM drop exceeds 175 RPM, slowly lean the mixture until the RPM peaks.8083-3, the FAA Airmen Certification Standards, Practical Test Standards, and the Pilot's Operating Handbook for the Cessna Skyhawk.

Cessna 152 stalling exercises with a 'wing drop'.The wing drops are around 2:50 and 4:00. A basic magneto drop-off check based on engine speed is typically done during the pre-flight inspection to determine the loss of engine speed that occurs when magnetos are switched from BOTH magnetos to one (LEFT or RIGHT) magneto. The maximum drop-off limit is specified in most Lycoming publications as Revolutions Per Minute (RPM) from a stated .CESSNA 172 CHECKLIST PRE-FLIGHT INSPECTION CABIN 1. Documents – A.R.R.O.W. 2.
