Airspace Structure; Human Factors; Procedure
Two events occurred while conducting the RNAV GPS 13 approach to LGA. The initial event was a flap overspeed (not exceeding 5 knots) at flaps 30 for 3-5 seconds due to gusts. Approximate altitude was 1800ft MSL. Approximate airspeed was slightly above 185 (possibly 187ks). The overspeed occurred as we were initiating a step down on the approach from RABBY @ 2000ft to MEATZ @ 1300ft. Pitch and power adjustments were made to resolve the overspeed. Almost immediately following the overspeed; we received a TCAS RA (monitor vertical display) to not descend into the red arc. We stopped our descent and initiated a slight climb which resolved the RA. The RA was resolved with a small altitude adjustment. We were able to quickly regain stabilized approach criteria well before the 1;000 ft. call and opted to continue the approach. Prior to the events; the approach was stable and un-rushed. We were on speed at flap selection; however; I believe the combination of initiating our descent; wind gusts and a slight delay in power reduction led to the flap over speed. In regards to the RA; I believe the conflict was due to VFR traffic traversing the area along the Hudson River. We noted that a commercial jet aircraft (immediately behind us on the same approach also reported an RA).
Pilot reported receiving a TCAS resolution advisory while on initial approach to LGA.
