Blanik L-13 elevator cable replacement
Greetings, group!
Our local club has a pair of L-13s. In one of them, we recently discovered a badly-corroded elevator cable. The corrosion area was located was approx. 15" aft of the bellcrank attachment, under the port-side, aft cockpit flooring -- *very* difficult to get to. It would appear from the extent of the corrosion that this particular spot was not noticed during annual- and/or 100-hour inspections. First, a heads-up to other Blanik L-13 operators: you may want to take a really careful look at the state of your elevator cables, especially in that 15"-aft-of-bellcrank spot on the port side cable. The small, semi-enclosed space in this area of the cable run is both A/ impossible to see without flashlights and mirrors (or an endoscope), and B/ exposed to moisture from e.g. wheel-thrown debris and cockpit condensation. Second: we've been told that new cables will cost $490.00 each (!) from Videck, and take upwards of 3 weeks to get here. I know aviation parts are rarely inexpensive, but $500+ (with shipping) for a 20-foot, 3/16" galvanized steel cable with eyes and swages seems exccessive; similarly-built Piper and Cessna control cables, while admittedly somewhat shorter, tend to run about $100. Does anyone know of a reason why a less costly option, like ordering some custom cables from Aircraft Spruce, wouldn't be legal/safe/ practical? Are there any other suggestions that might help our little non-profit club avoid or mitigate a potential bill of $2,000.00 for 4 cables, and a month-long grounding of our Blaniks while we wait for them to arrive? Thanks in advance, Brad |
