MALFUNCTIONS
A. Drogue entanglement with main
B. Drogue detaches from main
C. Horseshoe malfunction, drogue cannot be pulled
D. Horseshoe malfunction, drogue can be pulled
A. Drogue entanglement with the main:
PROBLEM: The drogue becomes entangled with the inflated main canopy. This may or may not create a problem.
REACTION: Ask yourself two questions: 1) Can I control the canopy? and 2) can we land safely without injury? If you
answer “No” to either question, then perform a breakaway by 2500 feet (750 meters).
ANALYSIS: If your main canopy opens in very deep brakes, or opens in a near-stall configuration, there is always the
chance the deflated drogue canopy will be thrown forward of the canopy’s nose and fall into the suspension lines.
This problem rarely calls for a breakaway because the deflated drogue creates very little drag.
B. Drogue detaches when release handle is pulled:
PROBLEM: Drogue canopy detaches when drogue release handle is pulled. The main may or may not deploy.
REACTION: If the main does not deploy, pull the reserve. The main will almost surely then be released and may deploy
fully. As soon as the reserve is fully open, cutaway the main.
ANALYSIS: This can happen when the drogue connection to the bag breaks or the connection from the canopy
breaks. These two spots have proven to be points of noticeable wear. If the PCA breaks you should still have a normal
deployment.
C. Horseshoe malfunction, drogue cannot be pulled.
PROBLEM: The main bag, for whatever reason, has deployed before the drogue has been thrown. Bag and lines are
out.
REACTION: Immediately throw the drogue. The main may or may not deploy normally. If not, proceed with emergency
procedures. Be aware of your altitude.
ANALYSIS: Study tandem fatality #10. Always operate the handles in the proper order.
D. Horseshoe malfunction, drogue cannot be pulled
PROBLEM: The main bag has somehow been deployed from the container prior to the drogue being thrown. The
drogue however, cannot be thrown for whatever reason.
REACTION: Release the RSL shackle and pull the breakaway handle. You may have to give the main risers a tug to
assist their release. Then pull the reserve ripcord.
ANALYSIS: Either the main container closing pin was accidentally dislodged, or the main closing loop broke. Care
should be taken when moving around inside any aircraft to protect the handles and the closing pins.
