Using a sample of $448.1\times10^{6}$ $\psi(3686)$ events collected with theBESIII detector, a search for the isospin violating decay$\eta_{c}\to\pi^{+}\pi^{-}\pi^{0}$ via $\psi(3686)\to\gamma\eta_{c}$ ispresented. No signal is observed, and the upper limit on$\mathcal{B}(\psi(3686)\to \gamma\eta_{c}\to \gamma\pi^{+}\pi^{-}\pi^{0} )$ isdetermined to be $1.6\times10^{-6}$ at the $90\%$ confidence level. Inaddition, a search for $\eta(1405)\to f_{0}(980)\pi^{0}$ in $\psi(3686)$radiative decays is performed. No signal is observed, and the branchingfraction $\mathcal{B}(\psi(3686)\to\gamma\eta(1405)\to \gammaf_{0}(980)\pi^{0}\to\gamma \pi^+\pi^-\pi^0 )$ is calculated to be less than $5.0\times10^{-7}$ at the $90\%$ confidence level.
