Narrative:

At an altitude of approximately 6000' MSL (4800' AGL), and 2 mi from the end of the runway, the captain cancelled IFR and initiated a rather radical visibility approach. The aircraft was slowed and gear and flaps extended. The captain rolled the aircraft to the left in excess of 60 degree bank angle and lowered the nose to 20 degree pitch. Crossing the runway centerline, he then did the same thing in the opp direction. Passing through 1000' AGL I called 1000' sink, 4000 FPM and no response from the captain. At approximately 500' AGL the captain pitched the aircraft up and left (leaving gear down and flaps 20 degrees) and the airspeed slowed to 120 KTS. I urgently called airspeed bank angle (power was back to near 0 torque), at which time he added power. We then landed on runway 23. The passenger complained to me as they disembarked about the 'wild ride.' after the captain came inside away from the aircraft, I told him of the passenger complaints. He then told me I was too critical of his flying and went and sat in the aircraft. I am a rated captain, type rated in this aircraft. I was on reserve and called in to fly with my chief pilot, who was the PIC at his insistence.

Title: FO REPORTING ERRATIC FLYING BY CAPT ON MARGINAL VISUAL APCH AND LNDG.

Narrative: AT AN ALT OF APPROX 6000' MSL (4800' AGL), AND 2 MI FROM THE END OF THE RWY, THE CAPT CANCELLED IFR AND INITIATED A RATHER RADICAL VIS APCH. THE ACFT WAS SLOWED AND GEAR AND FLAPS EXTENDED. THE CAPT ROLLED THE ACFT TO THE LEFT IN EXCESS OF 60 DEG BANK ANGLE AND LOWERED THE NOSE TO 20 DEG PITCH. XING THE RWY CENTERLINE, HE THEN DID THE SAME THING IN THE OPP DIRECTION. PASSING THROUGH 1000' AGL I CALLED 1000' SINK, 4000 FPM AND NO RESPONSE FROM THE CAPT. AT APPROX 500' AGL THE CAPT PITCHED THE ACFT UP AND LEFT (LEAVING GEAR DOWN AND FLAPS 20 DEGS) AND THE AIRSPD SLOWED TO 120 KTS. I URGENTLY CALLED AIRSPD BANK ANGLE (PWR WAS BACK TO NEAR 0 TORQUE), AT WHICH TIME HE ADDED PWR. WE THEN LANDED ON RWY 23. THE PAX COMPLAINED TO ME AS THEY DISEMBARKED ABOUT THE 'WILD RIDE.' AFTER THE CAPT CAME INSIDE AWAY FROM THE ACFT, I TOLD HIM OF THE PAX COMPLAINTS. HE THEN TOLD ME I WAS TOO CRITICAL OF HIS FLYING AND WENT AND SAT IN THE ACFT. I AM A RATED CAPT, TYPE RATED IN THIS ACFT. I WAS ON RESERVE AND CALLED IN TO FLY WITH MY CHIEF PLT, WHO WAS THE PIC AT HIS INSISTENCE.
