Narrative:

While being in cruise level flying IMC; I asked center to deviate for WX buildup to the west. At that time center gave me the altimeter setting '2991.' within 5 mins I was asked to rechk my altimeter setting. I saw my altimeter 8200 ft. While watching conditions of my wings I noticed I had some control issues and noticed a right flap (only) extension of approximately 5 degrees. Told center 'I seem to have an extended flap problem and it is hard to control the aircraft. Will I be experiencing any further WX (IFR-VMC) for the rest of my flight.' center replied 'yes heavy precipitation in vicinity and there is a good chance. Are you declaring an emergency.' my response was 'no; full control with minor difficulty. I will fly the present heading and try to fix it. But not long; I want to fix it before the gulf.' center said; 'roger.' approximately 5 mins later I called back with not repairing flap issue and asked where was the 'closest airport.' after various options given accepted tnt which was 15 mi east of my position. Center said 'cleared to tnt descend to the airport.' I said 'I will turn right and descend' but actually made a left turn that progressed into a spin. After recovering from spin I continued right turning descent. Asked control for tnt frequency. Conditions and runway lengths where given. Additionally was instructed to 'stay with center until safely on the ground.' on approach to runway 9 straight in I performed 2 retractions of flaps and gear did a low approach; and on short final approach I said '...I seemed to have corrected my problem.' center replied 'state intentions.' I said 'can I assume navigation to kkeyw?' center replied 'right turn direct kkeyw climb and maintain 6000 ft.

Title: M20 PLT EXPERIENCES AN ALTDEV; HAS A FLAP PROB AND DECIDES TO DIVERT. ON APCH TO DIVERSION ARPT THE PROB IS CORRECTED AND PLT PROCEEDS ON COURSE TO INITIAL DEST.

Narrative: WHILE BEING IN CRUISE LEVEL FLYING IMC; I ASKED CTR TO DEVIATE FOR WX BUILDUP TO THE W. AT THAT TIME CTR GAVE ME THE ALTIMETER SETTING '2991.' WITHIN 5 MINS I WAS ASKED TO RECHK MY ALTIMETER SETTING. I SAW MY ALTIMETER 8200 FT. WHILE WATCHING CONDITIONS OF MY WINGS I NOTICED I HAD SOME CTL ISSUES AND NOTICED A R FLAP (ONLY) EXTENSION OF APPROX 5 DEGS. TOLD CTR 'I SEEM TO HAVE AN EXTENDED FLAP PROB AND IT IS HARD TO CTL THE ACFT. WILL I BE EXPERIENCING ANY FURTHER WX (IFR-VMC) FOR THE REST OF MY FLT.' CTR REPLIED 'YES HVY PRECIP IN VICINITY AND THERE IS A GOOD CHANCE. ARE YOU DECLARING AN EMER.' MY RESPONSE WAS 'NO; FULL CTL WITH MINOR DIFFICULTY. I WILL FLY THE PRESENT HDG AND TRY TO FIX IT. BUT NOT LONG; I WANT TO FIX IT BEFORE THE GULF.' CTR SAID; 'ROGER.' APPROX 5 MINS LATER I CALLED BACK WITH NOT REPAIRING FLAP ISSUE AND ASKED WHERE WAS THE 'CLOSEST ARPT.' AFTER VARIOUS OPTIONS GIVEN ACCEPTED TNT WHICH WAS 15 MI E OF MY POS. CTR SAID 'CLRED TO TNT DSND TO THE ARPT.' I SAID 'I WILL TURN R AND DSND' BUT ACTUALLY MADE A L TURN THAT PROGRESSED INTO A SPIN. AFTER RECOVERING FROM SPIN I CONTINUED R TURNING DSCNT. ASKED CTL FOR TNT FREQ. CONDITIONS AND RWY LENGTHS WHERE GIVEN. ADDITIONALLY WAS INSTRUCTED TO 'STAY WITH CTR UNTIL SAFELY ON THE GND.' ON APCH TO RWY 9 STRAIGHT IN I PERFORMED 2 RETRACTIONS OF FLAPS AND GEAR DID A LOW APCH; AND ON SHORT FINAL APCH I SAID '...I SEEMED TO HAVE CORRECTED MY PROB.' CTR REPLIED 'STATE INTENTIONS.' I SAID 'CAN I ASSUME NAV TO KKEYW?' CTR REPLIED 'R TURN DIRECT KKEYW CLB AND MAINTAIN 6000 FT.
