I noticed there is a stc for extended baggage for the bc12d. When I read the stc it references the F-19. Id like to add the extended baggage stc, does anyone have any drawings or pics?

Re: extended baggage stc
Hi Plater,
You can't have an extended baggage compartment without putting a C-85 engine on a 4" longer mount (otherwise there will be a tendency to go aft cg).
There's lots of info on here about the STC to which you refer...search for "Harer". -
Re: extended baggage stc
I do have the C-85 engine but on the 65 hp mount.Comment

Re: extended baggage stc
Plater,
It is a weight and balance thing. You have to move the engine forward 4" to allow the extra weight in the baggage area. It is part of a larger mod that also increases the gross weight to 1500lbs by installing larger bushings in the wing spar where the attatch fittings bolt on. It is called the Harer STC, but is now owned by Terry Bowden on this forum. It has been discussed ad nauseum here. A search will turn up a lot of info.Richard Pearson

Re: extended baggage stc
Up until a recent total re-build, I had extended baggage and a C-85 on a short mount with no electrics. No problems with calculated weight-and-balance (even with the longer moment arm for the center of the baggage area). I was still way within the approved limits. I recommend you run some calculations and see what you come up with.
The extended baggage is ideal for light weight camping / winter gear / wing and engine covers / etc. With the extra space you could easily load over gross ... but be thoughtful about it and you shouldn't have any problems. I flew it that way for about 20-years and never a problem.
I now have the C85 with a long mount and electrics. Weight and balance still well within limits.

Re: extended baggage stc
Thats funny, I can put 200#'s in the aft of my extended baggage with the short mount and the CG is within spec. I actually weighed my aircraft and plugged in the numbers to calculate at gross and 400 over gross since 2 people and full fuel would put me over. actually me and full fuel is over...

Re: extended baggage stc
It is funny! You have to admit, it is probably one of the most consistently brought up topics on this forum. Regarding the weight and balance comment, I was referring to what is required of the STC to keep it legal.Originally posted by Bird View PostRichard Pearson

Re: extended baggage stc
I'm surprised, Tim. I can approach aft cg with the regular baggage compartment on my BC12D-cum-Model 19 with the nose tank approaching empty (the critical aft cg scenaro).
I've also flown beyond the aft cg (where the mains lift before the tailwheel does) and I don't want to go there again
I'd be interested to see your calcs (privately if appropriate).Comment

Re: extended baggage stc
One factor to consider is that the STC also places the battery at the back of the larger baggage compt. If you want to deviate from the STC by keeping the short mount, that would be fine if you have no battery or move the battery farther forward. The STC does not change the CG limits. This remains the responsibility of the Pilot to verify each flight.Terry Bowden, formerly TF # 351

Re: extended baggage stc
Limit is 50 pounds on my aircraft... W&B DATA AND EQUIPMENT LIST AMENDMENT is specific to your aircraft. As long as gross weight is not exceeded and baggage limitatation is not exceeded balance computations are not required.
Extended baggage has added an arm of +40 on my airplane. On floats at gross I am near aft CG limit. On wheels slightly aft CG.
Very easy to add too much weight to extended baggage...be careful! Placard and heed!
Just about ready to reassemble my Tcraft. As a matter of fact I am going to cut new floor boards starting this morning. She will be better than before and will look good close up too. A couple more months of part time work.
I am in the market for a good set of skis. so if anyone has a lead...? I am going to retire the Federals.Jim Hartley

Re: extended baggage stc
Remember the additional weight of the floor boards and bigger sling eats into the baggage weight! You have to do a new weighing to find the empty weight and new CG. DON'T CALCULATE IT! You may NOT actually have 50# available with a heavy sling or plywood box or floors. If I was thinking of carrying skis or fishing gear I would do a weigh in empty, then with the equipment I planned to carry to be SURE the W&B was right.
My 41 was CG aft when I bought her and way heavier than the W&B paperwork said. Nice BRISK and RESPONSIVE plane! Should have been, I was on or beyond aft CG half the time! I am sure glad I didn't do any spin work in it before I found out. The only reason I found the problem was I was looking at the TC and thought, "Wow, my plane has EXACTLY the weight and CG as on the TC!" That set off alarms like mad in less than a minute. DON'T TRUST OLD W&B PAPERS!!!! WEIGHT your plane!
