Hello,

What is the TBO for a TSIO-520-P6B? 1,400, 1,600, or 1,800 hours?

Can somebody help?

Thanks!
 
From old Aviation Consumer:
The 1,400-hour engines will make TBO, said one owner, but usually with one top overhaul. Mine was topped at 700 hours. Judging from Service Difficulty Reports, cylinder cracking is a matter to be reckoned with. Another owner said Suffice to say that most operators will have changed a couple of jugs by 800 to 1000 hours, so you might as we’ll plan for it.

Safe to say a high maintenance engine.

according to this document, https://flightcenter.aero/sites/default/files/docs/sil98-9e-tbo-continental.pdf, for the "old" Ps, 1400 or 1600 TBO;
so, the TSIO-520-P6B is good for 1600, right?

Read the notes:

1. If an engine consistently accumulates 40 or more hours per month since being placed in service, add 200 hours to recommended TBO.
2. Engines with Serial Number 1006000 or higher include an additional 200 hours to TBO (as noted in Table 1, column 3).

5. Applies to new and rebuilt TSIO-520-M Spec. 6, 7, and 8; TSIO-520-P Spec. 5 and 6; TSIO-520-R Spec. 7, 9, 10, and 11;New and rebuilt TSIO-520-M, P, and R model engines with subsequent specification numbers.TSIO-520-M, P, and R engines (except those listed above) may be eligible for a 1600 hour TBO increase by installing; new cylinder and valve assemblies P/N 646657A1, or superseding part number, pistons P/N 648044, or superseding part number, ring sets P/N 649227, or superseding part number, exhaust valve lifters P/N 646277, or superseding part number, throttle body P/N 649185A4, or superseding part number, CM P/N 646957, or superseding part number, R.H. magneto, P/N 646958,or superseding part number, L.H. magneto, P/N 636951, or superseding part number, Harness, or EQ6583 pressurized magneto and harness kit, oil pump assembly P/N 643717-1, or superseding part number, P/N 643749, or superseding part number, oil pump gasket, and oil filter with integral filter adapter P/N 649923 or, superseding part number. To install a new oil pump, remove one each P/N 402159 and P/N 402157 stud. Replace stud P/N 401852 with stud P/N402129P003 and install spacer P/N 646582-1.35 and P/N 646582-2.00 on existing studs after oil pump is installed. A logbook entry is required. Update engine data plate with the correct engine model and specification number as follows:TSIO-520-M(1) converts to TSIO-520-M(6); TSIO-520-M(2) converts to TSIO-520-M(7); TSIO-520-M(3) converts toTSIO-520-M(7); TSIO-520-P(1) converts to TSIO-520-P(5); TSIO-520-P(2) converts to TSIO-520-P(6); TSIO-520-P(3)converts to TSIO-520-P(6); TSIO-520-R(1) converts to TSIO-520-R(9); TSIO-520-R(3) converts to TSIO-520-R(10);TSIO-520-R(4) converts to TSIO-520-R(9); TSIO-520-R(5) converts to TSIO-520-R(10); TSIO-520-R(6) converts toTSIO-520-R(11).

so?
A TSIO-520-P6B is a converted TSIO-520-P, having at least 1600 TBO?

The current reference is the TCM Standard Practice Manual (M-0), Table 6-1. Its basically the same info from the SIL which was cancelled.

Is your engine a factory new or rebuilt -P6B? Is the engine serial number >1006000? If the answer is yes to both, the TBO is 1800 hours. And under Note 1, you can technically take that number to 2000. However, since you are posting here, I doubt that engine has flown 40+ hours per month since put into service.

I assume: rebuilt & serial < 1006000

Then 1600, based on that info per Note 5, but excluding Note 1. The only other TBO criteria out there, which I don't believe applies based on your model number, is TCM recommends a 1200hr/12mo TBO for engines used for aerial spraying.
